Linear guide rails endstop holder

To attach a endstop on our CNC machine we designed this holder, it should work for all axis that use linear guide rails. It's designed parametrically so alternation for different rails should be easy.
Update:

• Moved the endstop more to the edge, so that the machine doesn't hit the holder.
• Added a fastening hole on the top.
• Added endstop holes on both sides.
