For the new enclosure of my Prusa printer I needed a new filament spool holder. I wanted one that is fully 3d printed, but with bearings and also optimised for an enclosure (filament goes directly down). I didn't find one, so I designed this one myself.
For the gear bearings I used the great scad script from emmett. Thanks for sharing!
