Hand Crank 8mm Shaft NEMA23

This is a simple yet very functional hand crank for the back of a dual shaft NEMA23 8mm stepper motor.

The exact motor I used is here: http://www.ebay.com/itm/322128751249

You will also need a M3 socket head screw about 20-25mm long. I used a 30mm partial thread type and then cut the threaded section shorter so the handle is on the non threaded smooth portion. But I am pretty sure it will work just fine if you used it with a fully threaded 20mm long screw.
