I made this desiccant box to fit behind the filament spools inside dryboxes made from this storage 47 qt. tub. It also fits inside the build volume of the Prusa Mini (180mm cube).

I have one of these sitting snugly behind the spools in all my dry boxes.

Assembly:

• Print 3 parts as oriented (no supports)
• Glue the top on the body
• Fill with desiccant beads
• Screw on the top
