nema 23 Stepper 2 Proxxon MF 70 mount

Remixed from erdinger's http://www.thingiverse.com/thing:151185 Proxxon stepper motor mounts. I had some nema 23 steppers so, I wanted to hook them up to my Proxxon mf 70 micro mill. I also remixed the coupler since my motors had a small pin going through the shaft, which I thought would be useful in securing the coupler to the shaft. I also made a stabilising bracket/mount for what I have as the y-axis (the shorter axis), which is stationary. I noticed the stepper motor mount sagged a little and this bracket helps. This bracket has a radius that fits the round motors I have. I will update a bill of materials later but essentially what you need to change is the length of the screws for the mounting points (add 10mm to the original value).
