Mini Fang Integrated for Ender 2

V1 of mini fang remix for the Ender 2. I had to clip off one of the blower mounts to avoid hitting the x-axis. The duct also touches the hot end, so there's a chance the duct will melt :)

Just an update: After a few months of continuous use, the duct did not in fact melt, it just blows out a bunch of warm air from the left duct! If anyone is better than me at CAD, please feel free to extend the ducts so it can be moved ~2mm away from the extruder. Thanks!
