A remix of the fan duct made by carlol : http://www.thingiverse.com/thing:1973156

Redesigned to be used with 3x 30mm cooling fans and allow the heated bloc to go under the rear fan, like the original E3D V6 fan duct

The fans I used : http://e3d-online.com/Electrical/Fans/30x30x10mm-12v-DC-Fan

As you can see the left owl is almost perfect using these fans, unlike the right one printed without cooling
