Prusa Mendel i3 Z endstop Tuner

We needed a easier way to tuner the Z endstop on our Prusa Mendel i3, as reworked by eMotionTech (http://www.thingiverse.com/thing:119616).

The original Endstop, while being very solid was not easy to tune precisely.

So we took the idea of using a screw to tuner the relative position to the endstop and ... Voila ! ;)

Works like a charm and make our life much easier ! ;)
