Airtight Filament Container

Parts for adapting an airtight storage container* for holding filament while printing. It only works with narrower spools, like the ones used by NinjaFlex, Filamentum, Colorfabb, or Up!. I purchased it hoping it would work with the larger spools but it's slightly too for most 1kg spools.

Uses a spool roller inspired by the TUSH spool holder but prints in one piece and is sized for the spools mentioned above. Bearings are inserted from the bottom and should snap in place. Or you can use your favorite sit-on-top style spool holder.

The tube cap is optional, it's for terminating the open PTFE tube when not is use. A hole will need to be drilled through the lid of the container to install the bowden adapter.

If you're not sure if the spools you use will fit, the table of filament spool dimensions I've encountered may help.
