Filament Dry Box - Made from an ammo can box

thingiverse

You'll need: 1 Ammo Box (see dimensions below) A good supply of PTFE tube Print two "filament guides" Print two "spool holder" 1/2 inch Sch. 40 PVC pipe Some glue (I used CA) Ammo Can Box Internal Dimensions: 301 x 212 x 172 mm First, print two filament guides. Drill a hole in the box where you want the filament to exit. Make sure it's big enough for a PTFE tube to fit through. Glue each guide on either side of the hole using a small length of PTFE tube inserted through both guides and the hole. This will help align and center the holes. You may need to scale the guides to fit since different tubes come in various dimensions. It should fit snugly. Next, print two spool holders. The spool holder requires a section of 1/2 inch Sch. 40 PVC pipe, cut to about 160 mm long. Assemble them together. The spool holder should fit into the box as shown. Don't forget to add a container of desiccant to your new dry box. I use it to store and print nylon-based filaments.
