Micro Adjustable Z End Stop

This is based on my Micro Adjustable Bare Wire Z End Stop, which allows for very precise Z positioning. This variation still supports bare wires, but in the photo you can see I've just superglued a mechanical switch onto the side of it. It snaps onto the smooth rod and tightens into place with an M3 set screw (and trapped nut). The adjustment hardware is hidden by the knob.
