Another Ender fan Duct

A simple fan duct for the ender 2 using a 5015 radial blower fan. You will also need a 25+mm M3 screw and nut to attach the blower (although you can get away with a zip-tie in a pinch)

It mounts on [superpotatofudge's hot end cooling duct](https://www.thingiverse.com/thing:2160958), so you need to print that as well.

The blower can be wired to the k-fan output on the Ender-2 circuit board. Once installed and wired mine just worked - no firmware changes required.
