Hi & welcome to my first instructable - so please bear with me if i make any mistakes!
I wanted to store my 3d printer filament in a safe, dry container but still be able to use the filament straight from the box. So here it is, my version of a 3D filament dry box. I had an empty resealable box in the shed that had suet pellets in it for the wild birds, so I thought, hey i know what i can use that for!
Firstly I got a length of pipe and cut it to fit inside the box with about 6mm clearance on each side. Then I headed over to thingiverse & searched for a wardrobe (closet) bracket. The only one that i found that suited my needs was this : https://www.thingiverse.com/thing:2801062 (Thanks to Juscallmesteve). If you use a thicker pipe than i did then you may need to scale it up a bit!
I then drilled 4 holes in the sides of my box using a 4mm drill bit & then attached the brackets with the M4 bolts, nuts and a rubber seal each side. Then I made sure the pole fitted ok and slid on a couple of reels of filament to check clearance etc.
The next thing i had to do was to figure out a way to make holes for the bowden tubing but to keep it kind of airtight with no gaps. I could of simply just drilled some holes and inserted the tubing, but that i thought, would not be good enough, so off to thingiverse i headed to search for a bolt that would have a hole straight through. I found just the thing thanks to DarthxRinzler ! : https://www.thingiverse.com/thing:1750875 .
While i waited for them to print, I then drilled four holes into the front of my box. Then I attached the filament feeders not forgetting a rubber seal in each side of the bolts. Then I fitted a length of bowden tube through and it worked like a charm! I then chucked in some silica gel sachets and put the lid on. JOB DONE!
The only thing I had to do next was to take it all apart again, take photos as i reassembled it and then write this instructable!
If i forgot anything let me know in the comments :)
Below are the main supplies & I have given links to them. I am in uk so these are co.uk eBay links, but you should be able to find them in your country wherever you are!
3d printer or know someone who can print you two 3d printed bar mounts,
A piece of metal pipe, doweling or rigid plastic tubing that will fit nicely onto the anchors, i used a 12mm diameter piece of metal pipe cut to length of my box.
bowden tubing (I bought 5 metres),
silica gel packets (as many as you want)
Step 1: Step 1: Gather Everything Together
Gather all your parts together (list above) & make sure you have all the tools you need to hand. You will need the following tools:
A drill with a 4mm bit & a 7.5mm bit (I used ones for drilling wood).
A craft knife or your 3d printer snips.
A 1.5mm allen key.
4mm socket & 8mm socket or you could just hand tighten. (I over-tightened & snapped a plastic bolt so be careful).
A ruler or tape measure.
A fine tipped marker pen.
Step 2: Step 2: Cut a Piece of Tube, Dowel or Metal Pipe
Cut a piece of tube so its around 6-8mm shorter than the width of your box. Put it aside for now.
Step 3: Step 3: Drill Holes in Sides of Box
Using the smaller drill bit, drill 2 holes through one side of your box, ensuring that it is the right height & in the centre. You can use the piece of pipe with a reel of filament on it to guide you. Use a marker pen to mark where you need to drill the holes if you would rather do that.
Repeat for the other side of the box.
Step 4: Step 4: Attach the Bar Mounts
Clean off any burring with a craft knife or cutters. Attach a bar mount to one side of the box using the two of the M4 10mm bolts & 2 of the M4 nuts. Don't forget to put a rubber o-ring on each side of the bolts. Tighten using the allen key but DO NOT over-tighten.
Repeat this step for the other side of the box.
Take the pipe & some reels of filament to make sure it rests on the mounts well without hitting the sides or bottom of the box.
Step 5: Step 5: Drill the Holes in the Front
Use a marker pen & ruler to get a straight run, as you don't want them wonky like mine ! Ensure that the holes will be in line with the filament that will feed to it.
Now drill 4 holes into the front of your box where you marked it using the 7.5mm drill bit.
Remove any burrs with your craft knife or snips.
Step 6: Step 6: Attach the 3d Printed Bolts & Nuts
6a Grab a plastic bolt & nut
6b Put an o-ring onto the bolt
6c Place the bolt through a hole in the front of the box.
6d Put another o-ring on the other side of the bolt.
6e Attach a plastic nut but do NOT over-tighten - I made that mistake and had to print more !
Repeat all the above for the other 3 holes.
Step 7: Step 7: Fit the Bowden Tube Through
Get your bowden tubing & cut it into 4 equal lengths.
Push a length through one of the holes & then feed one of your filaments through.
Repeat for the remaining reels.
Chuck some silica gel packets inside & seal up the lid.
You now have a good 3D printer filament dry box to keep your filament in from getting moisture in it.
Lastly I would like to hope that you enjoy making this & if you do then please feel free to show it off in the comments below.
Also please let me know if I have made any mistakes or forgotten to mention anything!
