Openbeam Clip-on Endstop Holder

This was a quick build for my OB1.4 y endstop. I realized the endstop I was going to mount on the smooth rod was not going to work well and I didn't want to have to take apart the printer to put more M3 nuts in it so I created this snap on endstop holder. Its a mashup of the 15x15 cable holder and the Mechanical endstop V1.2 8mm bar holder.
