Nice! Can you make a shortened one for dual fan arrangement? (e.g. http://www.thingiverse.com/mak...

I put an extra nut between the nozzle and the aluminium to overcome  the warmth issue. Works great. This is one of the best designs. I tried the more direct nozzles but this one has the most air flow.

Maybe some airflow could be directed closer to the screws. For example thing:17602 (which is basically the original folded fanduct made with PLA, and very thin) has the screws even inside the airflow, which I guess cools the aluminium. It also has a smaller area of contact. However it doesn't push as much air through as your design.

Instructions

Print in the provided orientation, mount with the existing hardware.

I tried one of the fanducts that cool around the nozzle, but found they did not displace enough air. This design has an even more tilted fan placement, which should result in better efficiency.

It may look as if the duct blows on the nozzle, but this is not the case.

I added an extension from acrylic to mount another fan on the other side as the fan tends to favour the left side of the print. :)

UPDATE: due to heat from the alu cooling plate, the design was not stiff enough. I added some ribs to fix it. Also included the step file now.

The new design sagged under heat today as the fans were off for to long for an initial print at 230 deg print. Turned them on and managed to fix the fan-duct ;) I'm lucky i can print with the fan going on a heat bed.

Didn't print with it yet. But i had the standard piece of plastic you have to fold on it before so. No idea if this is any better.
