MK3 MK4 Filament Roller

MK3 MK4 Filament Roller. Replaces the standard side arm from the Prusa MK3, MK4 spool holder. Two 608 bearings needed per holder. bgcode files are sliced for MK4 and Devil Design PETG but printed fine on my brothers new MK4S. Slicer settings I used: Roller.stl - PETG Infill 20% Perimeters:3 Roller-Holder.stl - PETG Infill 25% Perimeters:4 Roller-Pin.stl - PETG default with brim Please note that the Roller-Holder has to endure a lot of stress, especially the 'fingers', therefore the 4 perimeters.
