Use this cap along with a short piece of 4mm OD PTFE to make a cap to hold the filament from falling inside a dry box.

UPDATE: on 05/22/2025, I updated the file for this filament cap with my latest version which works better with a wider range of filaments, from soft TPU to hard/brittle filaments.
I designed this filament cap to replace the one that came with the upside down filament drybox by GunplaMark. This cap address 3 issues I had.
- Brittle and breaks off if knocked from the side
- Tends to allow the filament to fall inside the drybox
- Difficult to release the retainer on the pneumatic fitting
After printing this piece, insert a short piece of PTFE, about 30mm long. I held the two parts with the PTFE down on a piece of wood and the used the butt end of a screw driver to tap on this cap, pressing them together.
This part has “nubs” inside it, on set to hold onto the PTFE, and one smaller set to hold onto a 1.75mm filament.
