Auto Level Bracket

I have a Prusa I3 variant. The extruder being used is http://www.thingiverse.com/thing:678089. The servo bracket attaches to the extruder. A 9g servo should friction fit into the slot.

if you rotate the model correctly, less support material is required. The servo slot should be parallel to the bed.

A micro switch is attached to the arm which is glued to the plastic servo arm.

I'm in the process of changing the design, but I'm not sure when that will happen.

I've changed the micro switch control horn. The previous one hit the bed when it retracted.
