Prusa i3 Dial Indicator Bracket for Bed Leveling

My version of a dial indicator bracket for bed leveling. Works on the folgertech prusa i3 stock y carriage. May work on others? Uses the stock nema 17 mount holes to mount the bracket.

See instructions for gauge specifics including measurements.

UPDATE 9/3/15 uploaded a new stl that looks a little better and uses slightly less material.
