Z Axis Adjustable Endstop - Folgertech Prusa i3

Adjustable z height endstop that glues onto x motor mount.

This is my combination of a few designs on thingiverse.

This design doesn't require any screws in the x motor mount or in the z motor mount which makes this easy to install.

1) Put 3mm nut into z screw holder.
2) Insert ~20mm x 3mm screw
3) Screw on 3mm knob to end of screw
4) Glue screw holder to motor mount. (I used crazy glue)
5) Attach endstop holder with endstop to z-axis smooth rod

The 3mm knob came from http://w
