Nema 17 Stepper Crank

thingiverse

A small hand crank for Nema 17 stepper motor. I was in need a easy way to turn the Z axis stepper motor on my Shapeoko 2 CNC, so here it is. The crank can accept shaft with 5mm diameter, and use 2 8mm~12mm M3 socket head screw, and 2 normal M3 nuts. Does not need support. Note: the slot for the M3 nuts were made a bit tight, which allowed me to insert heated M3 nuts for a solid fit.
