Filament Spool Roller 3000

This is a minimalistic spool roller that is also self-centering.

It can hold spools up to 130mm wide. Due to the curved rollers, the spool naturally centers itself in the middle over time.

It is designed to be a replacement for the Prusa MINI spool holder. 

Required hardware: 

• 4x 608 Bearings

Simply screw the pins into the sides, push the bearings into the rollers, and snap everything together. For better grip i simply taped some rubber to the bottom.

The pins are seperate from the sides so you don't need to replace the entire thing if a pin breaks.
