Tenok - the Adaptive Vacuum Cleaner

More than half of all vacuum cleaners are trashed while they still work. This project turns that trash into a resource: Tenok is a DIY-vacuum-cleaner that can be equipped with any used vacuum cleaner motor and hose!
You are the manufacturer, so you can use, repair and maintain tenok your whole life!

Making the wooden enclosure does not require elaborate wood-working skills and all other structural parts can be 3D-printed using a standard FDM-printer like a Prusa. All printed parts went through several iterations and are optimized for easy printing.

Though this instructable might look a bit intimidating because it has so many steps, give it a second glance: Yes it is long, but that is because there are no skipped steps and every task is explained in detail. There is nothing worse than starting to build something, just to realize that the instructions are insufficient – that doesn't happen here

Step 1: How It Owl Began...

Step 2: Tools

For this project you will need the tools in the picture that are listed below. I assume you get your wood cut to size where you buy it, so I did not add a table circular saw. It would also have been too big for the photo.

• ballpoint-pen
• pencil
• triangle-ruler
• metal ruler (preferably 40 cm or longer)
• utility knife
• scissors
• paper punch
• pliers
• cross screwdriver
• big clamp (For objects ≥ 25cm)
• 4x small clamps
• wood file
• bucksaw
• small chisel (8mm straight blade or smaller)
• jigsaw
• drillpress (a proper one works better than that in the picture)
• drills: Ømm = 2; 5; 8; 11; 20; 30; 40 (If you have no 40mm-drill, you can do that one with the jigsaw)
• soldering-iron + solder
• 3D-printer (preferably assembled, and not still boxed like in the picture)
• sewing machine
• strong hand sewing needle
• pins
• sand paper
• wood glue
• linseed oil (or your preferred wood-finish / wax / paint...)

Step 3: Materials

The material you need can be divided into seven groups:

1.) Used vacuum cleaner parts

Hose, pipe, floor-nozzle, motor, cables power-cord, power-switch and circuit-board (though we just want to keep the attached cables & cable shoes).

I will provide some additional information about suitable motors and switches in the coming steps

2.) Various used things

4x office chair castors, 2x obsolete bicycle tubes and a synthetic scarf or other polyester- or nylon-fabric (min 50x25cm)

Tip: Bicycle shops are a great source for old bicycle tube

3.) Household items

Aluminum-foil, 2.6m of rope (up to Ø6mm) or old shoelaces, strong thread and generic vacuum cleaner filter fabric

4.) Wood

You need 18mm-thick boards that are big enough, so you can cut out the rectangular pieces you need (see coming steps for sizes). I bought two 80x25cm boards and one 100x20cm board and cut them further in a maker-space. If you have no possibility to cut the wood yourself, buy it cut to size according to the technical drawing I provide later

5.) ABS- and PETG-3D-printer-filament

You need about 500g of each filament. It is possible to print the PETG-parts from PLA instead, but they become less flexible / break more easily

I printed the PETG parts in two different colours, but that is not necessary.

.

6.) Screws, nuts, washers

The wood screws must have a head that meets the shank in a 90°-angle (=the transition from head to shank may not be tapered). The given length does not include the head. The wood-screws should be dimensioned to be driven in Ø2mm-holes. If you are unsure which ones to buy, ask at the hardware store.

(82x) 16mm-wood-screws

(16x) 35mm-wood-screws (a bit shorter or longer is ok)

(98x) M4 washers for the wood screws. Make sure the screw-threads fit through them

The Hex-bolts should all be threaded across the whole shank:

(1x) M5 hex-bolts, 15mm long

(4x) M5 hex-bolts, 40mm long

(4x) M5 hex-bolts, 50mm long

(4x) M8 hex-bolts, 60 mm long; It can be difficult to find fully threaded M8 bolts in that size. However 50mm long ones will also work with most motors. I'll provide more info about which length is necessary for your motor in the coming steps

(13x) M5 Nuts

(4x) M8 Nuts

(12x) M5 washers, flat style

(8x) M5 washers, fender style (larger outside diameter)

(4x) M8 washers, flat style

.

7.) New electric components

There are two electric components you need to buy. One is a power regulator, that controls the motor speed and the other is a heat-sensor-switch (80°C-rated, NC) that turns the vacuum cleaner off when it gets too warm. I will provide further information about those two components in the next step.

Step 4: Finding the Right Components

Power regulator

The power regulator controls the speed at wich the motor spins. It works like a lamp dimmer, but is suitable for higher current. The two versions in the first picture, both fit into tenok's 3d-printed electronics-compartment, but you need to print different files, depending on which regulator you want to use (more info in the next step). If you find the smaller 2000W-version, buy that one. It is absolutely sufficient.

To find such a module online, try keywords like 2000W, dimmer, power / voltage regulator, speed control, PWM, ... as in the picture

_

Motor

Tenok is called an "adaptive vacuum cleaner" because the design does not rely on manufacturer-specific parts. You can use any motor from a disposed vacuum cleaner that looks similar to those in the second picture, is 97 to 131mm long and 97 to 150mm wide.

As tenok is not battery powered, but directly connected to the power grid, you can of course not use a small motor from a battery-powered device

I have seen vacuum cleaner motors online where the backside (the side facing up in the picture) looks different. Those would require a special adaptor, but they seem to be not so common and I did not find one yet. If you happen to find one, feel free to go ahead and design an adaptor – I'll add that version to the 3D-printer-files then

_

Hose

The hose is another part that tenoks design can adapt to. You can use found vacuum-cleaner hoses with an outside diameter up to 50mm.

A used hose – is that hygienic to use? Sure! – Cleaning hose, pipe and nozzle is easy: Just fill them with hot soapwater and shake them

_

Heat-sensor-switch

Heat-sensor-switches can be bought with different temperature-ratings and for tenok we need one that activates at 80°C (or in more precisely between 72 and 88 °C because of tolerance).

As we are running quite high current through the circuit, the switch should withstand at least 10A (ampere).

There are two types of those switches: One is normally open (NO) and the other is normally closed (NC). We need the NC-version because the switch shall let electricity through (=be closed) until it gets too warm and opens the circuit to stop the flow of electricity. Some vendors prefer to call the NC-version "opener", because it opens (opposed to a shutter) the circuit.

Switches like that are often labeled 80C NC 10A (80°C, normally closed, 10 ampere) or KSD80

_

Power-switch

The most common power-switch inside vacuum cleaners looks like the black and white models in the last three pictures. If you scavenge a switch that looks different, you will need to go on searching, because only this one fits at the moment.

The black power-switch in the picture fits right away whereas you would need to cut off the cap of the white one as in the last picture. It does not matter if the electric terminals come out of the bottom or the front – both will fit.

Step 5: 3D-printing

All print-parts for tenok can be printed on simple filament-printers like the Prusa i3 MK3S that has been used throughout the development of tenok. For the ABS parts you should put an enclosure around the printer / print-chamber to avoid warping.

The parts are designed for easy printing and only two of them require you to print a small amount of support material. Refer to the attached list to see which settings are necessary for which part.

All files you need to print can be downloaded from Thingiverse via this link:

https://www.thingiverse.com/thing:3710521

There are two parts where you need to choose a size, depending on which components you have scavenged / bought, namely print-parts PP02 (hose-adaptor) and PP14 (electronics compartment, upper part).

PP14: The 2000W-power-regulator (see previous step) works with PP14-s07 and the 4000W-version withPP14-s10. Essentially the two parts are identical, except for the hole where the power regulator is mounted because the bigger one also uses a bigger potentiometer with a bigger shaft.

PP02: You need to choose the version of PP02 that fits the hose you scavenged. I included adaptors for single spiral (PP02-sXX) and double spiral (PP02-dXX) hoses. Maybe helix is the correct word, but let's stay with spiral for simplicity. At first sight, single and double spiral hoses look pretty much the same, but you can easily distinguish them: You might have noticed that vacuum cleaner hoses have a thread that runs all around them. Follow it with your finger or a sharpie marker around the hose to see if it is a single thread or a double thread. Double thread means that two threads are running in parallel around the hose and if you follow one of the threads with your finger around the hose, you will notice with each turn that it looks as if you have skipped a thread, but that "skipped" thread is in fact the second thread that runs in next to the one you are tracing.
Hoses do not only come as single and double spiral versions, but also in different diameters, so I made 11 adaptors each for single (PP02-s30 through PP02-s50) and double (PP02-d30 through PP02-d50) helix. The two digits in the end stand for the hose diameter. Here are some examples:
PP02-s38 fits a single spiral (s) hose with a 38mm-diameter.
PP02-d42 fits a double spiral (d) hose with a 42mm-diameter.
Please also note: I modeled the adaptors in 2mm-steps because a 38mm-adaptor will also work for a 37mm-hose, so if you measure an odd number on your hose, just print the version that is next in size. To make it even clearer, I added the hose-size-range to each file-name like this: PP02-d38-PETG_2020-02-02_tenok_Hose-adapter_double-spiral_37-38mm

Step 6: Cut the Wood to Size

Cut your 18mm thick wood to the sizes given in the technical drawing.

If you do not buy the wood pre-cut, but cut it yourself think about a smart order, so you do not need to change the length-stop too often – many of the dimensions are identical.

Later you will need another small piece of wood (at least 130x20mm) to make the handle and while the grain direction is not important for the pieces we make in the current step, the handle needs to be grained in length, so try to save a 130mm long piece that is grained length-wise

Step 7: Arrange the Boards

Put the boards on the table in front of you as in the picture. For the next steps we do not need the two slender pieces so you can put them aside

Step 8: Pick the Nice Sides

Decide which sides of the wooden boards shall be on the outside of the vacuum cleaner. The ones that you put up now, will be the outside surfaces.

Step 9: Mark the Boards

Now mark the boards in the lower left corners with a pencilas shown in the pictures.

No worries, we will just sand the marks off in the end and they will not be visible on the finished vacuum cleaner.

In later steps I will refer to the workpieces by the NAMES you write on them now

Step 10: Flip Upside Down

Now flip the boards sideways like they were pages of a book so that you see the other, unmarked side of them. Do not flip them lengthwise or you will run into problems

Step 11: The Boards After Flipping

The unmarked backside of the boards should now be up

Step 12:

Now mark the backside of the boards in the lower right corners as you shown in the pictures.

Step 13: Draw Diagonal Crosses

REAR INSIDE / FRONT INSIDE / MOTOR:

Use a pencil to connect the corners of the square pieces with a line. The result are marks that form diagonal crosses through the center of the boards

Step 14: Draw Perpendicular Crosses

REAR INSIDE / FRONT INSIDE / MOTOR:

Draw horizontal and vertical lines through the center of the square boards. The result are perpendicular crosses

Step 15: Add Horizontal Lines

BOTTOM INSIDE / TOP INSIDE:

Draw horizontal lines positioned as in the drawing

Step 16: Add Vertical Lines / Marks

BOTTOM INSIDE / TOP INSIDE:

Draw vertical lines and marks positioned as in the drawing

Step 17: Vertical Mark

BOTTOM INSIDE:

Add a vertical mark

Step 18: Horizontal Mark

BOTTOM INSIDE:
Add a horizontal mark

Step 19: Ø8mm-mark

BOTTOM INSIDE:
Make a mark to drill a Ø8mm-hole

Step 20: Flip the Boards

ALL BOARDS:

Flip the boards upside down, so that they lie in front of you as in the picture

Step 21: Diagonal Crosses

REAR OUTSIDE / FRONT OUTSIDE / INLET:
Use a pencil to connect the corners of the square pieces with a line like on the other side of the boards

Step 22: Perpendicular Crosses

REAR OUTSIDE / FRONT OUTSIDE / INLET:

Draw horizontal and vertical lines through the center of the square boards.

Step 23: Mark Ø40mm-holes & Draw a Ø143mm-circle

REAR OUTSIDE:

Use a compass do draw a Ø143mm-circle in the center of this board

FRONT OUTSIDE / INLET:

Use a compass or make a mark to drill (or cut) Ø40mm-holes in the center of those boards

Step 24: Vertical Mark

INLET:

Make a vertical mark

Step 25: Ø8mm-mark

INLET:

Make a mark to drill a Ø8mm-hole

Step 26: Vertical Mark

TOP OUTSIDE:

Make a vertical mark

Step 27: Horizontal Marks

TOP OUTSIDE:
Make 3 horizontal marks

Step 28: Ø20mm-mark & 2x Ø30mm-marks

TOP OUTSIDE:

Make marks to drill a Ø20mm-hole and two Ø30mm-marks

Step 29: Drilling Through the Boards

Ø5mm: BOTTOM INSIDE / TOP INSIDE:

Drill (16x) Ø5mm-holes where the lines cross. In the first picture I circled all positions where you need to drill a 5mm-hole.

Ø8mm: BOTTOM INSIDE / INLET:

Drill (2x) Ø8mm-holes where you made a Ø8mm-mark before

Ø20mm: TOP OUTSIDE:

Drill a Ø20mm-hole where you made a Ø20mm-mark before

Ø30mm: TOP OUTSIDE:
Drill (2x) Ø30mm-holes where you made a Ø30mm-mark before

Ø40mm: FRONT OUTSIDE / INLET:

Drill (2x) Ø40mm-holes where you made a Ø40mm-mark before. If you do not have a Ø40mm-drill, you can carefully cut those holes out with a jigsaw instead (like in the next step).

Step 30: Cutting Out the Ø143mm-hole

REAR OUTSIDE:

If you happen to have a 143-mm drill that's very impressive and you can use it here.

Us normal mortals drill a hole (~Ø8mm) and cut out the circular Ø143mm-hole from there with a jigsaw.

Step 31: The Boards After Drilling / Cutting

By now the boards should look like this

Step 32: Arrange the Boards

For the next step, make sure that the boards are arranged in a way that all the INSIDE-marks and the MOTOR-mark are visible in the lower right corner like in the drawing

Step 33: Horizontal Lines

LEFT INSIDE / RIGHT INSIDE:

Add a horizontal line per board

Step 34: Vertical Lines

BOTTOM INSIDE / TOP INSIDE / LEFT INSIDE / RIGHT INSIDE:

Add a vertical line per board

Step 35: Trace the Screw-holes for PP1007

For this step you need the 3D-printed part "PP1007_Motorholder-Rear_wood-mounted-part". You can use the line-drawing in the beginning of the instructable to identify the correct part.

BOTTOM INSIDE / TOP INSIDE / LEFT INSIDE / RIGHT INSIDE:

Align the 4 printed parts "PP1007" with the marks on the boards:

the edge of PP1007 needs to be aligned with the horizontal mark.

PP1007 has built-in guides to mark the part's center that you need to align with the vertical mark.

Now trace the 8 screw holes (two per print-part) with a pencil

Step 36: Trace the Screw-holes for PP08

BOTTOM INSIDE:

Align the printed part "PP08_Cable-Holder-bottom_Outer-Part" with the marks on the boards. The screw holes lie on the vertical mark. The guides on the outside of PP08 need to be aligned with the horizontal mark.

Now trace the two screw holes with a pencil

Step 37: Horizontal Marks

TOP INSIDE:

Add two horizontal marks

Step 38: Assemble the Electronics Compartment

Next we want to trace the screw-holes of the electronics compartment. To do so, we need to assemble it partly first.

Gather the following 3D-printed parts:

• PP14_Electronics-Compartment_Upper-Part
• PP15_Speed-knob
• PP16_Electronics-air-inlet_Lid
• PP17_Electronics-air-inlet_Grid
• PP18_Powerbutton_Upper-Part
• PP19_Power-switch-Lock
• PP20_Powerbutton_Lower-Part

and also the scavenged power-switch and the power regulator module. Prepare the power regulator module by removing the plastic-knob that comes with it and unscrew the small nut from the shaft under the knob.

(If you do not have the electric components yet, you can do without the switch and use a simple potentiometer instead of the whole power regulator.)

Assembly:

1. Slide PP20 into PP14, so that it sticks out on the other side. You need to slide it in sideways first and when it sits in place, pull it through the circular hole. PP20 only fits one way: When you look closely at the picture you can see that it has a small recess on one side. Slide it in with this side first and it will work.
2. Screw PP18 into PP20
3. Slide the power-switch into PP14 so that it sits under PP20
4. Lock the power-switch in place by sliding in PP19
5. Insert PP17 with the tapering side first into PP14
6. Screw PP16 into PP14
7. Stick the shaft of the power regulator module's potentiometer through PP14 and screw the nut back on the shaft.
8. Put PP15 on the power regulator

Step 39: Trace the Screw-holes for PP14

TOP INSIDE:

Put the partly assembled electronics compartment on the board, and check the other side to align the interface carefully with the holes we drilled for it. When you deem the part properly aligned, trace the 4 screw-holes.

Please note: The more careful you align this part now, the nicer it will look assembled

Step 40: Trace the Screw-holes for PP1005

MOTOR:

Align the 4 printed parts "PP1005_Motorholder-Front_outer-part" one by one with the corners of the board and trace the screw holes (two each). To do so, use two small boards as guides to simulate the walls that will surround the MOTOR-board in the motor-chamber later

Step 41: Trace the Screw-holes for PP1001

MOTOR:

Align the printed part "PP1001_Turbine-Gasket-Holder" with the marks on the board. The screw holes lie on the horizontal and vertical marks. The guides on the outside of PP1001 need to be aligned with the diagonal marks.

Now trace the four screw holes with a pencil

Step 42: Trace the Screw-holes for PP11 & PP1009

FRONT INSIDE / REAR INSIDE:

Align the printed parts "PP11_Front-Hatch-Gasket-Holder" and "PP1009_Rear-Hatch-Gasket-Holder" with the marks on the boards. The screw holes in the parts' corners lie on the diagonal marks. Small built-in square holes in the parts serve as guides and need to be aligned with the horizontal and vertical marks.

Now trace the 16 screw holes (8 per part)

You might have noticed that this part has indicated additional screw holes. Initially I thought this part might be removed now and then to put new gaskets under them, so I wanted to provide an option to drill new screw holes ones the first holes are worn out. By now I am quite confident that the gaskets can last very long, but the indicated screw holes do no harm so I kept them

Step 43: Trace the Screw-holes for PP12

FRONT INSIDE:

Align the printed part "PP12_Bag-coupling" with the marks on the board. The screw holes lie on the horizontal and vertical marks. The guides on the outside of PP12 need to be aligned with the diagonal marks.

Now trace the four screw holes with a pencil

Step 44: Flip the Boards Around

ALL BOARDS:

Flip the boards around so that all the OUTSIDE-marks and the INLET-mark are in the lower left corners

Step 45: Trace Screw Holes for PP01

FRONT OUTSIDE:

Align the printed part "PP01_Hose-Coupling_Base" with the marks on the
board. The screw holes lie on the diagonal marks.

Now trace the four screw holes with a pencil

Step 46: Trace Screw Holes for PP1011

REAR OUTSIDE:
Align the printed part "PP1011_Outlet-Filter-Holder_outer-part" with the mark on the board. Two of the screw holes lie on the vertical mark.

Now trace the six screw holes with a pencil

Step 47: Trace Screw Holes for PP23

INLET:

Align the printed part "PP23_Central-Filter-Holder_Base" with the marks on the
board. The screw holes lie on the diagonal marks. The guides on the outside of PP23 need to be aligned with the horizontal and vertical marks.

Now trace the four screw holes with a pencil

Step 48: Trace Screw Holes for PP06

INLET:
Align the printed part "PP06_Cable-Holder-central-wall_Outer-Part" with the marks on the boards. The screw holes lie on the vertical mark. The guides on the outside of PP06 need to be aligned with the horizontal mark. Now trace the two screw holes with a pencil

Step 49: Horizontal Lines

REAR OUTSIDE / FRONT OUTSIDE:

Add a horizontal line per board

Step 50: Vertical Marks

REAR OUTSIDE / FRONT OUTSIDE:

Add two vertical marks per board

Step 51: Vertical Marks

TOP OUTSIDE:

Add two vertical marks on the center of the board

Step 52: Horizontal Marks

TOP OUTSIDE:
Add two horizontal marks (one of them is the extension of a mark you made earlier)

Step 53: Arrange the Boards

LEFT OUTSIDE / RIGHT OUTSIDE / INLET:

Flip the LEFT and RIGHT boards sideways and put the INLET-board in between so that they form the letter "H". Refer to the drawing for how to arrange the boards correctly

Step 54: Info

Later the TOP-board will be screwed and glued on top of the "H" we just build. That is why we will need small screwholes in this "H" that align with the bigger Ø5mm-screw-holes of the TOP-board.

In the next steps we will mark the positions for those small screw-holes.

Step 55: Horizontal and Vertical Marks

LEFT-side-surface / RIGHT-side-surface:

Add three horizontal marks per board

INLET-side-surface:

Add two vertical marks

Step 56: Vertical Lines

LEFT-side-surface / RIGHT-side-surface:
Add a vertical line per board

Step 57: Horizontal Line

INLET-side-surface:

Add a horizontal line

Step 58: Flip Boards Sideways

LEFT / RIGHT / INLET

Flip the boards upside down sideways. Refer to the picture to make sure you arranged them correctly.

Now you should again see the boards form a wooden "H", but with the unmarked side surfaces facing up.

Step 59: Apply the Same Marks

LEFT-side-surface2 / RIGHT-side-surface2 / INLET-side-surface2

Now add the same marks and lines on those side-surfaces as you did on the other side.

Step 60: Drill Into, But NOT Through the Boards!

Now we need to drill Ø2mm-holes into those boards.

Drill each hole about 13 mm deep. DO NOT DRILL THROUGH THE WOOD!

On the first two pictures I marked where to drill with green circles (and green arrows for holes you need to drill into the side surfaces of the boards).

For drilling into the side surfaces it's helpful to put up some sort of guide, to align the board to it like I did in the photo

Step 61: The Finished Boards

After drilling the boards are ready for assembly

Step 62: Putting the Box Together

In the following steps we will glue and screw the box together. When doing so, you can refer to the picture above for how to arrange the boards.

Tip:

Read through the next seven steps and put the box together without glue and screws and start putting it together for real when you have an idea how it needs to be assembled.

Glueing the box together should happen in one go, so the glue can dry out evenly afterwards. You do not have to rush through the assembly, but it's good practice to put the box together without interruptions – while not glueing it together the wrong way round.

Step 63: Arrange the Boards

Again form the letter "H" in front of you from the LEFT-, RIGHT- and INLET-board. Refer to the picture for correct postioning.

Step 64: Put the Box Together 1/6

Put glue on those surfaces of the INLET board that will be glued to the LEFT and RIGHT boards

Step 65: Put the Box Together 2/6

Place the INLET-board on the table with the gluey sides pointing towards the LEFT and RIGHT boards.

Before glueing the "H" together, also put glue on the surfaces of the three boards that point upwards

Step 66: Put the Box Together 3/6

Put the wooden "H" together and then put the TOP-board ... well, on top.

Naturally TOP-OUTSIDE should be on the outside of the box we are building.

Screw the TOP-board tight to the "H" with eight of the 35mm-wood-screws and 8 washers

Remove all the glue that has been squeezed out with a damp cloth

Step 67: Put the Box Together 4/6

Turn the half-built box upside down and apply glue to the surfaces of the "H" that point upwards now

Step 68: Put the Box Together 5/6

Glue and screw the BOTTOM-board to the "H".

Again BOTTOM-OUTSIDE should be on the OUTSIDE of the box we are building

Remove all the glue that has been squeezed out with a damp cloth

Step 69: Put the Box Together 6/6

Apply some force to the bond between the LEFT and RIGHT board and the INLET board by attaching a clamp to the box.

Putting some scrap-wood between the clamp and the box avoids clamp marks

Now you need to let the box rest, so the glue can dry – ideally for 24 hours, if you are patient enough, but over night is also OK. However you can already make feet for the box and glue them on (see next steps)

Step 70: And What About Those Other Two Wooden Pieces?

While the box dries you can already make it some "feet".

For that we will use the two slender wooden pieces we put aside earlier and remove some areas from them so we can run rope and the power-cord through.

Step 71: Mark the Wood

Start by making some marks on the wood and then flip the pieces, so that their side surfaces point upwards like in the third picture

Step 72: Lines

Draw a line on each of the wooden pieces. The 8mm in the drawing are measured from the edge of the surface we have marked before.

Flip the boards upside down and also draw lines on this side. Again the 8mm are measured from the surface we marked initially.

Step 73: Marks

Now you sort of extend the marks we made initially around the corner until they meet the long lines.

Again we flip the boards upside down and apply the same treatment to the other side

Step 74: Marks

Add some more marks near the edges

Step 75: Marks

And we also put marks on the smallest surfaces of the pieces and connect them with the marks we made in the previous step

Step 76: Hatching

Now we hatch all the areas we want to remove (see pictures).

Step 77: Saw and Chisel

Remove the wood from the inner hatched areas with the help of a saw and a small chisel.

Do not touch the hatched areas around the edges yet

Step 78: File

Now file of fthe edges until you are left with nice chamfers and the feet are done!

Step 79: Preparing the Box

If the glue of the box has already dried for some time (check the description on the glue you are using), you can remove the clamp and the four screws in the corners of the bottom

Step 80: Put Glue on Feet

Now apply glue on the surfaces of the feet that feature the longish cut-outs.

Do not put glue into the cut-outs

Step 81: Attach Feet

Align the feet with the edges of the bottom and clamp them to the box.

The foot with three cut-outs attaches to the rear and the one with two cut-outs attaches to the front (see drawing)

Next we want to drill holes into the feet, so you should let the glue dry for sveral hours.

Step 82: Drill Into, But NOT Through the Wood

After letting the glue dry, we can remove the clamps and make some marks in the corners of the feet.

The marks show where to drill 30mm deep Ø11mm holes for the office chair castors that we will use as wheels.

Do NOT drill through the wood – only drill 30mm deep into the wood.

PLEASE NOTE: Most office chair castors have Ø11mm-shafts, but some have Ø10mm-shafts. For those smaller shafts you should also just drill a Ø10mm-hole (otherwise you have to wind some tape around them, when attaching them)

Step 83: Remove All Screws

Now we prepare the box for sanding and remove all the remaining screws. Put them somewhere safe, as we will screw them back in later.

Step 84: Sanding

Sand of all marks and eventual glue residue

Step 85: Make the Ends Planar

The front and rear ends should be as planar as possible, so the hatches will close air-tight in the end. You can check if the ends are planar by putting something flat and rigid on them: If you see gaps you should grab a file and make work the ends planar.

Step 86: Making the Handle

The last wood working we have to do is making a handle for the vacuum cleaner. For that cut out a 130x20mm piece of wood. The piece needs to be grained in length, so it won't break under the weight of the vacuum cleaner.

(If you wonder why the piece in the picture looks broader than 20mm, that's because it is in fact broader. However I adjusted the dimensions for the final design that you are building)

Step 87: Line

Draw a line in the middle of the piece

Step 88: Marks

Make two marks

Step 89: Drill and Sand

Drill two Ø8mm holes where the line and the marks meet.

Afterwards sand the edges. The rounder you make them, the more comfortable the handle will be in your hand later on.

Step 90: Shielding the Motor Chamber

This step is especially important when you used coniferous wood like me as it can leak resin when it gets warm and you do not want resin to ooze into your motor, when the vacuum cleaner gets a little warmer.

That's why we make some aluminum foil shielding for the motor chamber that gets attached to it's top, bottom, walls and hatch.

Cut out pieces of aluminum foil in the sizes you find in the drawing, add the indicated cut-outs and also pre-fold the foil as indicated. After folding the pieces should fit well into the motor compartment. If they don't fit , tweak them a bit

Step 91: Putting Glue on the Hatch

Apply heat resistant glue (see below) evenly to the rear hatch's INSIDE-surface.

How to tell which side is the inside, now that the marks are sanded off? Easy: It has the screw holes for the rear-hatch-gasket-holder (PP1009).

PLEASE NOTE – Which glue to use:

I made some oven-tests with glue I already had to see if I need to buy special heat-resistant glue to attach the aluminum-foil to the wood and it turned out that my Titebond III Ultimate Wood Glue does the trick perfectly. If you can get this glue – great, use it! If not: Find some heat-resistant (at least 90°C) glue for this step

Step 92: Attach the Foil

Attach the foil and press it flat with your palm or the bottom of the glue container.

Do not fold the foil to glue it around the edges – you will later cut off the excess foil

Step 93: Cut the Circle

Cut the circle into strips, glue them to the side-walls of the circular hole and cut the tips of

Step 94: Cut Away Some Foil

Cut the foil at least 5mm (better 10mm) from the edge to avoid having a conductive bridge from the motor chamber to the outside later

Step 95: Prepare the Next Piece of Foil

Take the bigger piece of aluminum foil and fold its 20mm wide pre-folded areas flat on the piece. If you are unsure what I mean, compare this picture with the previous one

Step 96: Apply Glue

Apply glue evenly to the wall that separates the motor chamber from the bag chamber.

Step 97: Start Attaching the Foil

Now pick up the piece we prepared in the previous step, carefully place it in the motor chamber and press it flat to the wall we just put glue on

Step 98: Attach the Next Side...

Now apply glue to one of the walls and press the foil against it

Step 99: ...and the Other Side...

repeat the previous step with the opposing wall

Step 100: ...and the Remaining Strips

Now finish attaching this piece by glueing the 20mm wide folded strips to the walls

Step 101: Glue

Now we start to attach the last Aluminum foil piece.

Again, start by putting some glue on the wall that seperates the chambers (or more precisely on the foil that covers it now)

Step 102: Place the Last Aluminum Foil Piece

This piece needs to cover the walls that have no foil on them yet, so make sure to place it right.

Again we press the foil to the glue we have just applied

Step 103: Attach the Foil to a Wall...

Again apply glue to one of the yet uncovered walls and press the foil against it

Step 104: ...and to the Last Wall

And again repeat the previous step with the last uncovered wall

Step 105: Trim the 20mm Wide Strips

Now trim off the portion of the 20mm-wide strips that exceed the wooden walls

Step 106: Apply Glue

Apply glue to the rear end surfaces of the box and press the foil on them

Step 107: Cut Off Excess

Like with the hatch, cut the foil at least 5mm (better 10mm) from the edge to avoid having a
conductive bridge from the motor chamber to the outside later.

Rub some extra glue on the areas where the foil ends to seal them

Step 108: Cut Out the 40mm-hole

The title says it

Step 109: Find the Screw Holes

Now you need to find the hidden screw-holes under the foil and poke them with a screwdriver.

You can cheat by using PP1001, PP1005 and PP1007 as templates again. Also the holes in the hatch are easier to find with the help of PP1009 (not in the picture).

There are two holes in the TOP-board that you cannot find with the help ob the printed parts. If you do not remeber their location just go back and check where they are supposd to be.

Step 110: Finishing the Box

When the glue has dried properly, you can apply a finish to the wooden parts. I used linseed oil to keep the natural look of the wood, but you can of course use something else, if you like

PLEASE NOTE: If you plan to use some sort of delicate paint finish, you might want to quickly perform step 202-204 and drill the holes for the handle-holders (PP10) before you apply the finish. That way you avoid the risk of messing up the finished surface

Step 111: ??? – Three Things Are Odd!

There are three things you might wonder about when you look at the pictures:

1. Where did the printed handle holder (PP10) go?
2. Why does the wooden handle suddenly look strange?
3. What is that thing in the upper right corner?

The reason for those irregularities is that when I shot the photos for the tutorial, the vacuum cleaner had a differently shaped handle that did not require printed parts, but an old belt.

You can just ignore those details in the photos – In the end they will disappear and we mount the updated handle

Step 112: Preparing for Assembly

When you made it this far, I guess you are already excited to put the whole thing together. Preserve that feeling a little longer because we still need to make some parts before the final assembly and we start by making rubber shock absorbers and gaskets from bicycle tube.

Step 113: Get Some Tools

For making the rubber parts you will need the following tools:

• steel ruler & angular ruler
• ballpoint-pen
• paper punch
• pins
• sewing-needle & strong thread
• utility knife
• scissors
• pliers

Moreover you will need the 3D-printed turbine-gasket-holder (PP1001) and a small piece of cardboard

Step 114: Rubber Parts

There are five different rubber parts: Some are made from pieces of tube, others are cut out of the tube. In the next steps we will make the pieces one by one.

It does not matter how wide your tube is, but you can make your life easier by trying to find wide tube instead of very slender types like that used in racing bikes

Step 115: Frontal Shock Absorbers

We start by making shock absorbers for the frontal motor holders.

First cut a 75mm long piece off the tube

Step 116: Punch Holes

Use a paper punch to make a hole on each side.

Tip: Often tubes have seam-lines that you can use as a guide so your holes end up on the same height.

Tip 2: When you remove the bottom of the hole punch you can see more easily where you are punching

Step 117: Make 8 in Total

Repeat the last two steps 7 times, so you have 8 shock absorbers in total

Step 118: Rear Shock Absorbers

Cut a 57mm long piece off the tube and punch a hole on each side

Step 119: Make Six in Total

Repeat the previous step 5 times, so you have six rear shock aborbers in total

Step 120: Hatch Gaskets

First measure how wide your tube is when you press it flat on the table.

The length of the pieces you want to make is 230 minus the width of the tube, so if you measured for example 40mm, then you need to cut off 190mm long strips (because 230-40 = 190)

Now calculate how long your pieces need to be and cut one off

Step 121: Cut Three More

Now that you know how long to cut your rubber pieces, make three more of them and place them on the front hatch like I did in the picture

Step 122: Cut Four More

If you are happy with the pieces you made in the last step, make four more for the rear hatch

Step 123: Turbine Gasket

To make the motor gasket, we need to cut the tube open.

Bicycle tubes are usually curved because wheels are unfortunately round. This makes it a bit tricky to make flat, even rubber sheets out of them. For that reason I found that it works best to cut it open at its peak.

If the tube has seamlines, cut along one of those. They serve well as guides for the cut

Step 124: Cardboard Template

Lay the cut-open bicycle tube flat on the table.

Now take some cardboard and cut a 78x78mm square piece from it.

Use the cardboard as a template and trace its shape on the rubber.

(If your rubber piece is not wide enough, you can still use it. The pieces you make will just not have the exact length in one direction)

Cut out the rubber-square

Step 125: Trace the Central Hole

Put the rubber square in the printed turbine-gasket-holder (PP1001) and trace the hole in the middle on it

Step 126: Cut Out the Hole

Use scissors to cut out the hole you traced in the previous step

Step 127: Make 8 and Pin Them

Make seven more of those rubber pieces so you have eight in total.

Stack the pieces on top of each other, make sure that the holes are aligned and pin the stack together

(If your rubber sheet was to short to cut proper squares, rotate every second piece, so that the stack becomes squareish)

Step 128: Sew the Stack

Take your sewing needle and stitch the corners of the stack with strong thread. It requires some force to pull the needle through, so I used pliers to grab it.

The knots of the thread can later rest in the small pockets of the printed turbine-gasket-holder (PP1001)

Step 129: Cable-holder-gasket

Like the motor-gasket, this part is also made from a sheet of rubber, so we cut a bit more tube open along a seamline.

Step 130: Cutting

From the small rubber sheet we cut out a 20x50mm piece and use the scissors to cut out a small hole (~Ø3mm) in the center

Step 131: Finished Rubber Parts

Now the rubber parts are finished and we can move on to the next step

Step 132: Filters

Get your generic vacuum cleaner filter fabric, a compass, scissors and a ruler

Step 133: Micro Filter

In the package you find two sorts of filters: micro-filter and motor filter, which is more coarse.

We start with the micro-filter-fabric: Get out the compass a draw a Ø132mm-circle on it

Step 134: 3 Different Filters

Now cut out the circular filter you traced on the micro-filter-fabric.

From the coarser motor-filter-fabric we make two more circular filters: One is Ø125mm and the last filter is quite tiny with just Ø24mm

To sum it up:

Micro filter fabric – Ø132mm

Motor filter fabric – Ø125mm; Ø24mm

Step 135: Finished Filters

The filters are finished, so we can move on to the next step

Step 136: Electrical Components

Now we will prepare the electrical components. I know that this topic often feels alien and intimidating in tutorials, but don't worry, I made it quite easy to follow

Step 137: What We Are Aiming For

In the end we will have this circuit in the vacuum cleaner:

An on/off-switch, which is connected to the power regulator that controls how fast the motor is running and a heat-sensor-switch to turn everything off when it gets too warm – that's it.

Step 138: Preparing Scavenged Parts

On the first picture you can see how the components were connected in the vacuum cleaner I took them from. In your case it might look a bit different, but that's fine.

First we separate all the parts.

We do not need the circuit board, but we are interested in the cables that are attached to it. Cut off the longest cable (incl. cable-shoe) and keep it. Remove three cable-shoes from the remaining cables and keep them

Step 139: Add Components

Now we add our power-regulator and heat-sensor-switch. As we see in the diagram, the functional components are already complete, but the connection between them is not.

We'll fix that in the next steps

Step 140: Make the Missing Cable

Cut off 50cm from your power-cord.

This small piece of cord will connect the power-regulator with motor & heat-sensor-switch

Remove about 50mm of the power cords's outer sheathing and from each end of the piece you cut off, so that the inner cables are revealed. Now remove about 3mm of cable-sheathing from each cable end.

Step 141: Soldering I

Solder one cable shoe to one of the cables in the power-cord. It does not matter to which of the two cables you solder it.

Step 142: Soldering II

Solder the remaining two cable shoes to the two cables in the 50cm-piece we cut from the power-cord.

Step 143: Finished Electrical Components

Now the electronics are ready to go into tenok. On the third picture I connected them to give you an idea how the circuit looks.

Step 144: (The Step That Should Not Be)

Remember that I wrote that I changed the handle design after I made the photos for this tutorial?

Well, in the original version you would now have to cut the old belt to size and punch holes into it, but as our final handle will look different, we skip this step. I just included it, so you do not get confused by that ominous brown strip that appears on the next photos

Step 145: Making the Bag

I am by no means a professional at sewing, but making a drawstring-bag is luckily one of the easisest things you can make and is often recommended for absolute beginners. That's why there are also a lot of instructions online about making such a bag, so I decided to just link one of them here. The linked tutorial does not use an old scarf, but a towel instead, but close enough I would say. You can of course also look for another drawstring-bag-tutorial and follow that one – I just did a quick search and there might be better ones.

I might make a separate tutorial about sewing a small drawstring-bag in the future, but for now using another one is just fine

Step 146: ASSEMBLY STARTS!

Now it's finally time for assembly!

As a first step the 35mm-wood-screws that we removed for sanding are screwed back into the box.

Step 147: Attach 4x PP1005

Attach (4x) "PP1005_Motorholder-Front_outer-part" in the corners of the motor compartment witch two screws and washerseach

Step 148: Collect Parts for Frontal Motor Holders

Now that the outer parts of the frontal-motor-holder are mounted, we can prepare the inner parts. For that we need:

• (4x) PP1006_Motorholder-Front_inner-part

• (4x) M5 hex-bolts, 40mm long
• (4x) M5 hex-bolts, 50mm long
• (8x) M5 washers, fender style (larger outside diameter)
• (12x) M5 Nuts

• (8x) frontal shock absorbers (rubber part)

Step 149: Prepare Inner Parts of the Frontal Motor Holders

Put two nuts into one of the four "PP1006_Motorholder-Front_inner-part". One goes in from the side and one from the back (first picture).

Loosely screw a 50mm-M5-hex-bolt into the nuts in the printed part (second picture).

Wrap two off the rubber-shock-absorbers around the printed part (third picture).

Put a fender washer on one of the 40mm-M5-hex-bolts, put it through the rubber and the printed part, put a fender washer on the end of the bolt and screw the whole package tight with an M5-nut (fourth picture)

Step 150: Install 4x PP1006

Repeat the previous steps with the remaining three inner parts of the motor holder and once all four inner parts are finished, slide them into the outer parts that are already screwed into the box

Step 151: Mount Heat-sensor-switch

Use two screws and washers to attach the heat-sensor-switch to the TOP-board of the motor chamber

Step 152: Mount PP1001

Attach "PP1001_Turbine-Gasket-Holder" with 4 screws and washers

Step 153: Attach 4x PP1007

PLEASE NOTE: Before you mount this part, mage sure that the M8-hex-bolts fit into them. If you cannot slide them in completely, work the parts with a utility knife or similar

Mount (4x) "PP1007_Motorholder-Rear_wood-mounted-part" to the four side walls with two screws and washers each

Step 154: Bag Chamber

Turn the box around, so you see the bag chamber

Step 155: Attach PP14

Attach "PP14_Electronics-Compartment_Upper-Part" with 4 screws and washers

Step 156: Attach PP08

Attach "PP08_Cable-Holder-bottom_Outer-Part" on the bottom inside the box with two screws and washers

Step 157: Attach PP06

Attach "PP06_Cable-Holder-central-wall_Outer-Part" with two screws and washers

Step 158: Attach PP23

Attach "PP23_Central-Filter-Holder_Base" with 4 screws and washers

Step 159: Attach P22 to P23

Slide "PP22_Central-Filter-Holder_Grid" into the central-filter-holder-base we installed in the previous step.

Take a close look at the two parts to see how you need to orient the grid so it fits into the base

Step 160: Top of the Box

Turn the box so you see its top surface

Step 161: Attach 2x PP04, But Read First

PLEASE NOTE: Before you attach the cord-pins you might want to skip to steps 202-204 and drill the holes for the handle-holders (PP10) first. Like that the Cord pins are not in the way when you measure where to mark the screw holes, but you can also do it later when you arrive at this step.

Attach (2x) "PP04_Cord-Pin" with a screw and washer each

Step 162: Attach Front Hatch Gasket and PP11

Attach "PP11_Front-Hatch-Gasket-Holder" and (4x) rubber hatch-gasket-pieces to the front hatch with 8 screws and washers. Make sure to lay the rubber pieces on the front hatch the way I did, so each piece is fixed with a screw on both sides later. In the first picture you can see how they need to be arranged.

When you screw the screws in, push the printed part down firmly on the rubber so that it does not move around when you drive the screw through it.

Step 163: Attach Rear Hatch Gasket and PP1009

Like in the previous step, attach "PP1009_Rear-Hatch-Gasket-Holder" and (4x) rubber hatch-gasket-pieces to the rear hatch with 8 screws and washers.

Step 164: Power Cord

Pull the power cord through the central square hole of the box's rear foot and then through the Ø8mm-hole in the bottom.

As you can see in the diagram, our electronics start to come together: The heat-sensor-switch and the power-cord are already in!

Step 165: Attach PP09

Put one of the cable tighteners (PP09) on the power cord. The threaded part of the tightener needs to point towards the cable holder that is mounted on the bottom of the chamber.

For all the cables I found the central hole of the cable tighteners was big enough, but if your cable does not fit through, get out a drill and show that 3D-printed thing who's boss

Step 166: Attach Cable Gasket & PP07

Place the rubber cable-gasket in the already mounted outer part of the Cable-Holder (PP06) on the central wall that seperates the motor chamber from the bag chamber. It will stick out on both sides but that is fine.

Now pull the rubber a bit apart and slide "PP07_Cable-Holder-central-wall_Inner-Part" into PP06.

Step 167: Install the 50cm-cable

Now take the 50cm-cable that we cut off the power cord earlier. Push and pull the cable through the Ø8mm-hole in the central wall between the chambers. Make sure that the side with the cable shoes is in the motor chamber in the end.

You need to get the cable through the cable holder and in there through the little hole in the rubber piece that we installed in the previous step. This requires some effort.

If you can't make it happen, cut the hole in the rubber part a bit bigger, but make sure it still sits tight around the cable

Now that the big cables are in, we can soon install the funtional electric components

Step 168: PP09: Attach Two More

Attach one more cable-tightener (PP09) per cable. The threaded part of the tightener needs to point towards the end of the cable.

Step 169: Attach Cables to PP13

Screw the two cable tighteners loosely into the lower part of the electronics compartment (PP13).

It does not matter, which cable goes where, but mounting is easier when the power cable that comes from the bottom is attached closer to the end of the part

Step 170: Connecting the Power-switch

Get the power swich and attach the scavanged cable with the single cable-shoe to one of its terminals (it does not matter which) and connect the other terminal to the power-cord's cable that also features a cable shoe.

Step 171: Install the Power Regulator

The power regulator has 4 terminals: two of them are labelled "IN" and two of them are labelled "OUT". The designations might be slightly different, but as long as it is clear where the power goes in and where it goes out that's fine.

Attach the two cables from the power cord and switch to the "IN"-terminals by unscrewing the terminal a bit and fastening the revealed cable-end with the terminal screw.

Attach the other two cables that go to the motor chamber to the "OUT"- terminals

Step 172: Partly Assemble the Electronics Compartment ...again

Now that all functional parts in the electronics compartment are connected, we can put everything together.

When you do not remember what goes where just go back to the step where we assembled the electronics compartment for the first time

Step 173: Installing the Power-switch & -button

Again we

1. Slide the lower part of the power-button (PP20) into the upper part of the electronics compartment (PP14)
2. Screw the upper part of the power-button (PP18) into PP20
3. Slide the power-switch into PP14 so that it sits under PP20
4. Lock the power-switch in place by sliding in the power-switch-lock (PP19)

Step 174: Mounting the Power Regulator

Again we mount the power regulator as we did earlier. You can use pliers to tighten the nut on the shaft

Step 175: Closing the Electronics Compartment

Now it's time to close the electronics compartment: Hook the back of the lower part into the upper part and screw the front of the two parts together with the 15mm-M5-hex-bolt, two washers and a M5-Nut.

You can also tighten the cable-tighteners now. While you tighten them, grab the cable, so that it does not turn so much together with the tighteners

Step 176: Attach the Cable With 2x PP05

Now attach the power cord under the box with (2x) "PP05_Cable-Clamp" and two screws & washers each.

You can put them where you like.

You can pre-drill screw holes or if you used soft wood just rambo them in without

Step 177: Connect the Heat-sensor-switch 1/2

In the motor chamber, grab the cord that comes out of the central wall and attach one of it's two wires to the heat-sensor-switch that we mounted earlier

Step 178: Install Turbine-gasket

Place the rubber turbine-gasket on the turbine-gasket-holder (PP1001)

Step 179: Connect the Heat-sensor-switch 2/2

Find the scavenged wire with a cable-shoe on each side and connect one of them to the terminal of the heat sensor switch that is still free.

As you can see in the diagram, only the motor is missing now to have a closed circuit

Step 180: Attach 4x M8-hex-bolts

Slide the (4x) M8-hex-bolts from behind into the four parts of the rear motor holder (PP1007) that we mounted to the wooden walls earlier. Screw a M8-nut and washer loosely on each screw

Step 181: Put the Motor In

The motor should sit tight between the four rubber-damped frontal motor holders. You can adjust the position of the motor holders when the motor is not mounted. You do so by screwing the screw that goes through the inner part of the motor-holder in and out.

Test fit the motor and when it is to loose screw the afforementioned screw a bit out and test fit the motor again. Repeat this until the motor sits tight. You should still be able to slide the motor in and out comfortably with your hands. If you have to get a rubber hammer, it's definitely too tight.

Make sure that all the motor-holders are screwed to about the same position, so the motor sits in the middle of the box

Now all the functional parts and cable connections are in the box. In the next step we will finally connect the motor and close the circuit.

Tip:

If the turbine of your motor has a very inconvenient shape (for example a protruding metal collar exactly at the height where the motor holders end) that prevents you from mounting it properly, try to slide some extra rubber-bits under the rubber-padding of the motor holders. That way you should be able to create a shape that works with your motor

Step 182: Connect the Motor

Connect the remaining wire that comes from the box's central wall to one terminal of the motor (it does not matter to which).

The other terminal connects to the single wire that is already attached to the heat-sensor-switch.

Congratulations, the circuit is closed!

Step 183: Collect Parts for the Rear Motor Holder

Now we collect the parts to put the central piece of the rear motor holder together. For that we will need:

• (2x) PP1002_Motorholder-Rear_Motor-Adaptor_Slider
• PP1003_Motorholder-Rear_Motor-Adaptor_Base
• PP1008_Motorholder-Rear_Celtic-Cross
• (6x) rear-motor-holder-shock-absorber (rubber part)
• Strong thread

You can already slide the sliders (PP1002) into the base (PP1003), just like in the second picture

Step 184: Put the Collected Parts Together

Make two stacks of three rubber parts each, place them on the "celtic cross" (PP1008) and put the motor-adaptor (PP1003) on top. The holes in the corners of the adaptor should approximately align with the holes in the rubber parts and holes in the celtic cross

Before we fix the motor-adaptor to the celtic-cross, check if it will align well with the mounting-holes in the back of the motor. If it doesn't, you can rotate the motor adaptor on the celtic cross. There are multiple positions in which it can be mounted

As soon as you are happy with the position of the adaptor, thread a strong thread through each of its corners, the underlying rubber parts, and the nearest hole in the celtic cross beneath it.

Tighten the threads with a bow. Do not make knots yet because we want to tighten the threads further later on.

Step 185: Complete the Rear Motor Holder

Attach the contraption we just built to the motor

Remove the nuts and washers from the M8-hex-bolts

Put the bolts through the celtic cross

Attach nuts and washers again and tighten the nuts by hand so that the motor is held in place well. We do not want to tighten them too much though. I recommend to use no tools to tighten the nuts – what you can achieve with the strength of your fingers should be good enough

Step 186: Tighten the Threads

Now that everything is pressed together nicely you can open the bows, tighten the four threads that hold the rear-motor-holder together and make knots instead

Step 187: Secure the M8-nuts With 4x PP1004

slide (4x) "PP1004_Clip-for-M8-screws" on the M8 nuts. To do so you need to place the clip on a bar of the celtic cross and push it towards the nut so that it slides onto the guide rails (on the sides of the bar) and around the nut

Step 188: Attach PP12

Attach "PP12_Bag-coupling" to the inside of the front hatch with 4 screws and washers

Step 189: Attach PP01

Attach "PP01_Hose-Coupling_Base" to the outside of the front hatch with 4 screws and washers

Step 190: Attach 2x PP04 (front Hatch)

Attach (2x) "PP04_Cord-Pin" to the front hatch with a screw and washer each

Step 191: Attach PP1011

Attach "PP1011_Outlet-Filter-Holder_outer-part" to the outside of the rear hatch with 6 screws and washers

Step 192: Attach 2x PP04 (rear Hatch)

Attach (2x) "PP04_Cord-Pin" to the rear hatch with a screw and washer each

Step 193: ​Put the Air Filter In

Put the biggest of the filters we made earlier into outlet-filter-holder we attached in the previous step

Screw the inner part of the outlet-filter-holder (PP1010) into the outer part that holds the filter

Step 194: Electronics Compartment / Air Inlet Filter

From above, put "PP17_Electronics-air-inlet_Grid" into it's place in the electronics compartment

Now put the small filter we made earlier on top of the grid

Finally screw "PP16_Electronics-air-inlet_Lid" on top of the filter. You can use a coin as screwdriver.

Step 195: Attach PP15

And again we attach "PP15_Speed-knob" to the axle of the power regulator

Step 196: Put the Motor Filter In

Put the last filter into "PP21_Central-Filter-Holder_Lid".

Screw the lid together with the filter onto the filter-holder-base (PP23)

Step 197: Prepare Rope

Cut off two pieces of rope, each 120cm long

Step 198: Attach the Frontal Rope

Thread the rope through the square holes in the frontal foot and knot them together.

Put the front hatch on the box.

Wind the rope around the cord-pin (PP04) on top of the box.

Pull the cord arount the two cord-pins (PP04) on the front hatch

Step 199: Attach the Rear Rope

Repeat the previous step with the rear hatch on the other side of the box

Step 200: Attach Castors

Attach the castors by pressing their rods into the holes we drilled in the feet of the box

Step 201: Her Comes the New Handle!

The next step is to attach the handle and because the design changed after I took the photos for the tutorial, I decided to redo and take photos of the remaining steps with the new handle. So say Goodbye to the piece of belt and say hello to the new handle design.

For the handle you will need to cut a 37cm long piece of rope

Step 202: Open the Hatches

The title says it.

Step 203: Apply Marks 1/2

Apply marks to the top surface according to the drawing

Step 204: Apply Marks 2/2

Apply further marks to the top surface

Step 205: Drill Into, But NOT Through the Wood

As we did earlier, drill some Ø2mm-holes into the wood where the lines meet.

Drill about 13mm deep into the wood. Do not drill through the wood!

Sand the marks off and apply some linseed oil (or other finish, if you used something else)

Step 206: Attach 2x PP10

Attach (2x) "PP10_Handle_Holder" with four screws and washers each

Step 207: Attach the Handle

Make a knot in the end of the 37cm-long rope.

Thread the rope from below through one of the handle-holders (PP10) and twice through the handle like in the picture.

Thread the rope from above through the other handle-holder and make a knot in the other end

Step 208: Attach the Bag

Tie the bag to the bag-coupling (PP12) on the front hatch with a bow

Step 209: Attach the Hose

Close the hatches again
