PolyBot Servo Mount

This derivative has a couple of enhancements over the original to satisfy some overly restrictive constraints.

For the Renosis DeltaBot, he created a servo mount which had an offset to allow the arm to swing below the plane of the platform (http://www.thingiverse.com/thing:7554). That's a good thing.

This thing takes the design a bit further and adds both an offset, and a downward angle. This gives the arm a much broader range of motion without interfering with the edge of the platform.
