M8 Precision Rod holder - NEMA 17 stepper

This is a short attempt at creating a 2-in-1 precision rod holder that can use the NEMA 17 stepper motor. There are two possible placements of the motor, one of them needing the bracket to be used.

In the linear actuator configuration, you simply use the bar holder on top of the NEMA 17, and then use your choice of clamp to secure a threaded rod to the motor shaft.

In the belt configuration, you can use the provided bracket to attach the NEMA 17 to the back of the bar holder and run the b
