If you have an umbilical that goes all the way from the toolhead to the electronics bay and can't be bothered to redo the wire path, these cable cutouts let you just slip the existing wires into the endstop relocation mount. I've attached a 1.1mm version for diy cables using up to 20awg silicone insulated wire, 2mm cutout for 18awg silicone wires and a 5mm version for those using the thicker premade wires from BTT or chainflex etc.
Use two M3x8mm SHCS for attaching it to the A-Drive.
