Z axis opto switch

A support for optical endstop with fine regulation.
The support is designed for an omron sx4009-p1 e66 because I just had it from scratch. Unfortunally my ABS reflect the light of the emitter so I had to put a metal plate to switch off che emitter, bad to see but it works.
It is composed by 2 part. The fixed one and the adjustable part which allow you to slide up and down the switch.
