Mini modular keychain container

Multipart knurled container with cap that you can connect to your keychain. Outer threads have a slot for o-ring (tested with 9x2 & 10x2) but can be used without. I cannot promise watertightness but my tests are promising and seems to keep water out pretty well with the o-ring attached. You can stack as many middle parts as you want or use none and have small single container. Outer diameter: 19.2 mmContainer height: 20 mm (25 mm with outer thread) Tested with Bambu PLA basic and PETG HF, both has worked flawlessly for me.
