Remixed http://www.thingiverse.com/thing:1330490/ from cmidgley and added a screw hole to his version of MPCNC_Optical_End_Stop_IE_Short.stl.
I also added a small plate, so one can use this version as z stop mount.
You can put a M8 washer between "Middle End" and the plate to achieve a better alignment.
