Filament Palletizer I made. Uses up to 4(608RS) bearings and an 8mm drill bit You don't have to use all 4 bearings, You can instead just use two (Each on the outside) I recommend You print this model in strong filament aswell as A 100% INFILL! The filament will cut a hole into the inner walls otherwise. Use a vice to push in all 4 Bearings! For the inner ones, use a pointy bit on the vice to really push them in. Ignore the tape on mine, Printer wasn't configured correctly.

Printer used is a Klipper modified Anycubic Kobra! Have fun :3
