Dial guage clamp for RepRapPro Prusa Mendel Mono and Tricolour

This handy little bracket attaches to the extruder carriage of a Mendel Mono or Tricolour (the latest version as of July 2013, not the previous version with the horizontal carriage). You can then attach a standard 8mm shaft dial guage as shown.

Note that I have the bracket upside down in the photo.
