Extended arm for (adjustable z endstop)

When I was building my prusa I2, I had my friend print me out the adjustable z endstop from jedynak Thing 16380. I didn't realize it was for opto endstops, so i modified it to accept my tiny mechanical endstop switch's. I finally got around to modifying the stl file and printing out a new arm that should have better accuracy than what I had rigged together.

The arm is extended out a little bit as well so as to clear nuts/heads of bolts.

no new vitamins necessary.
