Sovol Filament Roller

Yet another filament roller: This one works for Sovol S01 and Sovol S04 printers.
It fits in the stock filament holder opening & uses two ball bearings for smooth operation.

Parts needed:
1x thread rod M8, 10 cm
2x bearings 608 ZZ 8 x 22 x 7 mm
2x washer M8
3x hex nut M8 OR 3x square nut M8 (print matching outer part)

Print outer roller ("Rolle") & outer part ("HalterAussen-*kant") with support.
Print either outer part for square nut ("HalterAussen-Vierkant") or outer part for hex nut ("HalterAussen-Sechskant").
Print inner tube ("Lagerrohr") with brim - I used 8mm.


Assembly instructions:
Remove stock cylinder from filament holder. Mount outer part (red) & inner part (violet) with thread rod, washer and two nuts. Screw tightly. Mount first ball bearing (yellow) into top opening of outer roller (green) - be sure to keep correct orientation - this part of the outer roller has an opening to overlap the inner part slightly. Mount outer roller to thread rod & add inner
