Gear extractor / puller for NEMA motors
thingiverse
This is a tool that makes you able to extract the pulleys / gears that come attached to the NEMA motors from factory (old printers, scanners, office copy machines, etc) against itself, without damaging the motor inners. I choosed M4 screw due the NEMA shaft diameter (5mm). IMPORTANT: Print this piece at 3 shells and 30% infill, and do not rotate or it won't come up strong enough to withstand the needed strength. Print Settings Rafts: No Supports: No Resolution: 0.2 / 0.3 Infill: 30%
