Flashforge 5M /Pro low friction spool holder. Two rolls with roller bearings provide low spool friction and improve filament feeding. Two rolls insure for unwanted spool spinning and filament unwinding.
For assembly need 4 roller bearings 5x10x4 mm (MR105.2RS) and DIN912 M3 6mm and 12mm screws or similar. Screws just for additional strength.
Printed PETG with 0.4 nozzle layer 0.2 mm. Printed without supports.
