Endstop Z axis for Prusa i3 Hephestos

*clefranc*'s endstop Z support didn't fit the circuitboard and the X-carriage on my prusa i3 Hephestos. I still liked the idea a lot though.

I decided to create my own version. I've included the openSCAD file, feel free to adjust the design.

(In the pictures you can also see a [adjustment screw][1] which allows fine adjustment of the z-axis)
