Sherpa prusa mini

I modified some of the original prusa mini parts for the Sherpa mini extruder. The mod uses 2 m3 square nuts and an m3 hex nut (not including the Sherpa extruder itself). You will not be able to home the printer withing around 40mm of the z top as it will collide with the stepper mount.

I haven't tried this mod by the way as I don't have a prusa mini, just thought they seemed like a great fit. I will test print it and make sure that the parts print alright though all I have at the moment is tpu.
