NEMA 17 Stepper Motor Optical Breadboard Mount

This is a NEMA 17 stepper motor mount that can be used on an optical breadboard for experiments and prototyping.

The distance between the mounting slots is 2 inches to accommodate an optical breadboard with 1 inch hole spacing.

I have made two of them so far (2016/07/29) for two stepper motors and they are well balanced and have a decent tolerance on the mounting holes and mounting slots. Mounting slots can accommodate possibly up to 1/4"-20 bolts and smaller. (Have not tested with 1/4"-20
