Bed probe holder for RepRapPro Tricolor/Mono Mendel

This part mounts on top of the X carriage to hold a microswitch for a bed probe. The switch is held in place by friction, and is turned by hand to lower and raise the probe.
The probe itself is a thin metal rod attached to the switch by careful bending of the rod and the metal strip of the switch (look at the picture closely).
The rod goes through a hole drilled in the bottom of the carriage cover. At the bottom, it is bent into a hook to not damage the bed.
