Nema 17 stepper motor mount

I needed a conversion plate to mount a nema 17 stepper motor onto a nema 23 mounting point. This was in relation to a hobby CNC milling machine that I have, where I am fiddling around with ideas for a 4th axis. I couldn't find exactly what I wanted on Thingiverse so figured I would create my own.

Whilst fiddling around I decided to create several nema 17 mounts, which would allow a stepper motor to be mounted at different heights away from the nema 23 location. I think this might potentially
