Simple micro switch holder for an endstop.

I used this on one of my CNC routers I built, but could easily be used on 3D printers.

The switch is a tight fit into the hold on purpose, but it does go in. I made the holes on the side line up with the holes on the switch and it's the perfect size to put some 1.75mm filament through and then just melt the end with a lighter or heat gun and press flat and it holds the switch perfect. The switch is tight enough that I've not used anything to hold it in and haven't had a problem also. There are braces in the back that stop the switch from going in to far. I pressed the switch in with some plyers grabbing the edge of the switch and the holder and squeeze and it was fairly easy.

Once the switch was pressed into the holder, I soldered the wires on which is easy, there is plenty of room to get to the terminals.

There is a single slot for a screw/bolt to hold it and allow to adjust distance a bit.

I was able to print this with the opening for the switch facing down with no support and 20% infill. Prints very quick since it's so small.

These are the micro switches I used: Amazon.
