I created this spool holder to ensure a smoother rolling of the filament spool.

I printed this model in Prusament PETG Jet Black with the 0.2 SPEED profile.

To finish the assembly you need two 8x22x7 bearings and two washers with 8mm inner diameter.

Every part except the main roller needs to be printed twice.
