Filament roll holder

Compact filament holder for smooth unwinding – even with non-AMS-compatible or third-party spools. Minimal material usage, fast printing, but please use a high infill (at least 30%) for the necessary stability.The design ensures that the filament spool sits securely on the ball bearings and does not slip between the holder and the bearing – no readjustment necessary.Caution:Ball bearings (Ø 22mm outer, 7.7mm inner, 7mm thick) are required.Superglue is required to secure the two printed half-shells.
