Customize Filament Spool Bearing Arm for Afinia / Up 3D

A filament spool bearing arm for the Afinia H series and Up Plus line of printers, based on emmett's amazing gear bearings.

The rendered STLs are for the Afinia value line of filiment spools. If you're using incompatible spools, or if the tolerances are too close, the dimensions and tolerances can be easily changed via Customizer.

Please note that this is complete overkill, but also completely worthwhile.
