Filament drybox for 4-5 spools

thingiverse

I made this drybox: I bought: - Plastic box (230x440x240mm, but measure your filament spools to fit them inside) - 4x PC4-M6 Pneumatic Straight Connector - 4x M6 bolt (matching the Pneumatic Connector you choose) - Few metres of PTFE tube (depending on how far away from your printer the drybox will be) - 16x M3 bolts (had them lying around, so different sizes) - 16x M3 nut - Lighter - Paperclip - 40mm round PVC pipe (has to fit the inner hole of your spools) - Some silica sachets I printed: - 2x PVC holder - 3x PTFE Tube holder by hilleke (https://www.thingiverse.com/thing:2614777) Thank you! Step one: Get a box that will close properly and fit your spools. Get the rest of the stuff. Print the holders. Step two: Measure where you want holes for filament to be. Unfold paperclip, use lighter to light red hot, make holes in box using paperclip. Make holes just measured places. Try pneumatic connector in hole; otherwise use hot paperclip again. Do this for all 4 holes. Put M6 nuts on other side of pneumatic connector. Step three: Measure where you want PVC holders to be (in middle of side should work). Use paperclip to make holes in box, try them with M3 bolt. Once all holes are there, use M3 bolts and nuts to screw holders onto box. Step four: Get 40mm PVC pipe, measure length from holder to holder, saw it to length. Step five: Put spools on 40mm PVC pipe, put it in box. Cut PTFE tubes to same length, connect them to pneumatic connectors on box. Put filament through pneumatic connectors and PTFE tube. Put silica sachets inside box, close it. Enjoy!
