Autolevel / Dual Alu Extruder carriage for printrbot plus

This is my new extruder carriage for my printrbot LC+ v1. It's designed to accomadate all those cool new features, including the ALU extruder and the auto bed level sensor. Should print and press together just fine with a .5mm nozzle. Smaller nozzles may have looser part fittings. Designed to use original hardware, with the exception of M3x20 screws to hold the fans on. Mounts directly onto the 4-screw attachment point.

NOTE: This is quite imperfect. The autolevel holder only mounts such that it's blocking you from seeing the probe, and needs to be redesigned. The back plate was made a bit too tall, so the top plate has bumps to compensate. Ideally the back plate would be the right size so the top plate could be flat! May come in a future revision.
