Monoprice Maker Mini Skateboard Bearing Filament Roller

thingiverse

This is half of a filament spool roller engineered specifically for the first-generation Monoprice Maker Mini Select printer. It's designed to accommodate a standard skateboard bearing and clip securely onto the folded metal spool holder that comes with the printer. The 1 kg AIO Robotics filament spool should fit neatly over one half, allowing it to be loaded onto the holder before the two halves are brought together to support the spool on the bearings. I've also designed a variation featuring a clipping retention system for the bearings, which will keep them firmly in place, but if issues persist with breakage, this simpler design is recommended.
