Opto Endstop X Adjuster

I ve made this for the Opto Endstops shipped with my Prusa Mendel Kit. These tiny Endstop PCBs have SMD light barriers and only one hole to fix. So i planed in a slot to prevent the PCB from rotating.

Todo:

- a wheel for the adjusting screw.
- maybe print the opto bar in an other direction, because the slot for the square nut gets filled while printing horizontal.
