Monoprice Maker Mini Skateboard Bearing Filament Roller 2

thingiverse

This is one half of a filament spool roller for the first generation Monoprice Maker Mini Select printer. It is designed to have a standard skateboard bearing added and to be clipped onto the folded metal spool holder that comes with the printer. The spool that 1 kg AIO Robotics filament comes on should fit over one and be able to be loaded onto the holder before the two halves are brought together to support the spool on the bearings. I also designed one that has a solid boss to hold the bearing if you have issues with the bearing clips breaking.
