adjustable mechanical endstop z for prusa mendel i2

adjustable mechanical endstop z for prusa mendel i2 for easy setting of z-zero-position => please have a look at the description for assembling the adjustable endstop (pdf-file in "Thing files") => I made an adjustment for nozzle-height which works much better as setting the zero-point in z with this endstop adjustment! Please have a look at my other uploads!
