Nimble V1 Robo3D quick release mount

This is the initial design for a quick release mechanism that will fit on a printer like the Robo3D to mount an E3D V6, using the Nimble extruder.
The quick release mechanism makes it easy to quickly mount and un-mount the hot end by using a rotating wedge to clamp the Nimble base plate against the back wedge.
The wedge is shaped in such a way that it locks the base plate in 2 directions.

Edit: The Cam Clamp and the Nimble Mount plate are now adjusted and will fit perfectly on the Robo3D X carriage as designed by lurkinturtle. (excellent work by the way!)

The Back Wedge plate, needs to 3 mm holes to be drilled in the X Carriage. The front Cam Clamp can be bolted using the existing 4 mm hole.
