I wanted to be able to use the original endstops + their wiring in my E3CNC so I designed these custom belt clamps. They are a directly drop in replacement to the original belt clamps, and you can screw in the original end stops.
You will need some m3 screws / plastic self tapping screws, but you should have spare from the initial teardown of the machine.
Print one of each clamp. You need one for left side and one for the right side for the Y axis, and one for the X axis.
