A simple protector for square Hall-O endstops. It has a small footprint, so it's suitable even on a Prusa i3 Z-axis with large metal couplings. A hole over the adjustment poti has been included.

It should be printed with clear or translucent plastic, because there's no extra hole for the status LED - and it just looks nicer...

Works nice in combination with my Hall-O Endstop Mount:
