I wanted the reuse my ender 3 steppers to build The 100, so I attempted to remove the press-fit pulleys with a few printed models, shear force, and heat. None of that got the pulleys to even budge. That's what brought me to create this model, a printable lead screw coupler that fits around the pulley.
There are two versions
- Long Motor Coupler: works for the motor with a 21mm shaft
- Short Motor Coupler: works for the motor with a 16mm shaft and should also theoretically work for the 21mm too
- Both versions should leave the lead screw at the same height if you want to use both pulleys for dual Z like I am with the 100
Hardware Required (Per Motor):
- 4 16mm M3 Screws
- 4 M3 Nuts
Print Settings:
- Orientation: Lay the long flat side down on the print bed (See image)
- 3 perimeters
- No supports
- 25% Infill
- Material: PLA
