Adjustable Z Endstop for MakerFarm Prusa i3v Remix

I based this off this design: http://www.thingiverse.com/thing:336665

I made it because the endstops Makerfarm sent me have a shorter -
metal clip thingy(really don't know what it's called, sue me) and it didn't reach the screw with the original part clough42 designed.
