Monoprice Maker Mini Skateboard Bearing Filament Roller 2

thingiverse

This is one half of a custom filament spool roller designed specifically for the first-generation Monoprice Maker Mini Select printer. It's engineered to accommodate a standard skateboard bearing and be clipped onto the folded metal spool holder that comes equipped with the printer. The spool holding 1 kg AIO Robotics filament should fit snugly over this half and can be loaded onto the holder before the two halves are brought together to support the spool on its bearings. Additionally, I've designed a second version featuring a solid boss to securely hold the bearing in place for users who experience issues with the bearing clips breaking or failing to retain their position.
