Nema 17 adjustable endstop bracket

I needed a bracket to mount a mechanical switch and be able to adjust position until I found the optimum so I made this one.

If you can't find the right position with this bracket, perhaps you need a different switch arrangement! :-)

It is a new design, not based on anything out there.

Other parts designed for my printers include:
