Prusa i3 Cooler with Bed Autolevel

This cooler will cool the J-Head extruder with a 30mm fan that I keep always on and a 40mm fan controlled by the Ramps board. It has a notch behind the 30mm fan to allow for wiring. The mounting plate for the J-Head will also accommodate a micro-servo for the bed auto-leveling feature in the latest Marlin firmware.
