MPCNC: Re-Improved Endstop Switch Mount

As part of entombing the endstop PCBs in epoxy, I tweaked the switch mounts to (optionally) eliminate the screw holes and (definitely) rationalize the spacings:

The sectioned view shows the cable tie slot neatly centered between the bottom of the switch terminal pit and the EMT rail, now with plenty of meat above the cable tie latch recess. The guide ramp on the other side has a more-better position & angle, too.

A trial fit before dabbing on the epoxy:

The 3M black foam tape works wonderfully well!

After the epoxy cures, it’s all good:
