Adapter to use a 7mm diameter pulley on an MK8 aluminium direct drive extruder. Tested with 1.75mm filament.
Reducing the filament pulley diameter form 11mm to 7mm allows to use motors with less torque.
There are two versions: open and closed (more restricted filament path).
Extra parts needed:
- 7mm diameter filament pulley
- 1x 624ZZ bearing
- 1x M4x8mm flat head screw
- 2x M4 nut
