Z Endstop

This is a Z end stop that mounts to the X Idler and replaces 1 of the Z axis 10mm shaft cap.

It has 2 nuts to keep the screw straight and keep it from unwinding (I also used a spring).

With the M3 screw you get 0.5mm per 360 deg turn.

I have included the RS Designspark Mechanical files so it can be edited if needed.
