80mm cooling fan for Mk8 dual extruder by Geeetech/ LEDs

This is an 80mm fan mount for the pre assembled Mk8 dual extruder by Geeetech. I would like to thank "bmxorcist" he was the one that inspired me to do this mod to my Hictop Aluminum Frame printer. I used his his firmware update and his "Prusa i3 Dual Mk8 X Carriage" (http://www.thingiverse.com/thing:1347192). I was not happy with not having any fan devoted to cooling the extruder, so after trying some other designs with multiple fans I came up with this. This design uses one 80mm fan to cool
