Limit Switch Holder for MPCNC

My MPCNC rails are ~23.5mm (give or take .2mm) and these are a snug fit even before the screw reaches the inserted square nut.

When upgrading to the dual end-stop firmware for the MPCNC, I wanted to avoid removing the bolts holding the bearings in place to replace the roller plates. I also wanted to avoid running more wires through the gantry conduits as it would have required modifications to my wire management.

Print these with three perimeters and ZERO infill. Set perimeter extrusion width to .45mm. Layer height was set to 0.2mm for mine but other layer heights should work fine. I used 5 layers on top and 4 on the bottom. There are no overhangs that would require support - the screw holes have cut-aways that will print clean with these settings.

I printed these with eSun PLA+ and there's more than enough flex in the part to allow it to easily slip over the conduit. I haven't tried with regular PLA but it should work fine.

When installing, insert the switch before tight
