Step 1: Making Cutting Data (for CNC Routers)

First, let's make machining data with CNC router
(If you make it by hand, please DL the data, then print it and paste it on the material.Then please cut with a cutter.
The blue line is a line that makes a groove. The red line is a tear line)

  1. Enter the size of the material. (In the case of Corrugated Cardboard 3 mm)
  2. Set the drill to V-bit and set to cut the blue line by 1 mm.
  3. Set to cut the red line at 3.2 mm.
  4. Set the hole to be opened with 3.2 mm

Step 2: Cutting Shell Parts

When you have data, cut the material.(In case of shopbot)

Move the shopbot with the data created in Step 1.

Cut out each required number of parts.

Step 3: Cutting Joint Parts

Cut the MDF(5.5mm) with a laser cutter

Cut out each required number of parts.

Step 4: Assembly

Let's assemble the cut parts.

Joint parts from A to X are fitted in 2 parts for each side of each shell part.

Everything is completed and it is completed

Step 5: Option Seat

Please cut the mdf 2.5 mm with a laser cutter and assemble it.

    Well done! I'd like to see how you'd solve waterproofing.

    corrugated cardboard or the solid kind? Would it be easier to join the pieces together with zip ties?

    As far as I can see zip ties wouldn't work as these joins not only pull together but also push apart, whereas zip ties would only pull together, there would be nothing keeping the edges from overlapping.

    Translation was inadequate.It is corrugated cardboard.
    In order to fix the angle between the parts, I think that a joint part is necessary.

    Zip ties is not tried, so it may be able to do!

    This would be great in some kind of UV resistant sheet plastic, then it would be usable outside or in and make a great play space for kids. You could even have transparent sections for windows. Have you thought about producing a run of flatpack kits for sale?
