Auto Level Bracket

thingiverse

I've got a Prusa I3 variant, and I'm using an extruder from http://www.thingiverse.com/thing:678089. The servo bracket snaps onto the extruder, with a 9g servo fitting snugly into the slot when aligned correctly. To minimize support material, simply rotate the model to position the servo slot parallel to the bed. A micro switch is attached to an arm that's glued to the plastic servo arm. I'm in the process of tweaking the design, but no timeline has been set yet. I've already swapped out the micro switch control horn - the previous one would sometimes hit the bed when retracted.
