Cupcake CNC Y-Axis Stepper Motor 40mm Fan Mount and Duct

This is a combination fan mount and duct that mounts a 40mm fan to the back of the x/y carriage to blow air across the y-axis stepper motor under the carriage. This motor was getting hot on me during long prints and this thing solves that issue. I have uploaded .sldprt, .iges, and .stl files. I created this in Solidworks 2010.

UPDATE Jan 9, 2013: I reworked the file such that it's Z-Up instead of skewed. It should have the fan mount flange down now.
