Hotend fan duct for Anet A8

This hotend fan duct is for a specific Prusa i3 variant - ANet A8.

The original kit came with a standard 40mm blower fan. It was ok for a lot of cases but couldn't get sufficient air moving when I wanted faster cooling for difficult shapes.

I replaced it with a much stronger 60mm fan. Also I built this duct so that the air will flow in different directions. It solves the problem that material on the side opposite to the fan didn't get enough cooling power.
