Makerfarm I3V Hexagon cooling

This is a improved fan duct, and x carriage for hexagon hotend. The stock cooling was causing my ABS prints to warp, so i designed this for the stock 40mm fan but to route the air through the back of the x carriage.

After doing this upgrade, you may find PLA not printing very well. The reason is the main fan is no longer cooling the print(bad for PLA good for ABS). So here is a print cooler to go with this. http://www.thingiverse.com/thing:764476
