Wide Mouth Fan Duct for Ultimaker
by owen, published
Suitable for V2 Nozzle.
Clearance is 3mm to platform and 2.5mm to heater block.
May be suitable for dual extruders (Untried yet)
Push on and Nut Mounted variety.
Updated Both Fan Ducts May 16/2013 (better wall thickness. Firmer fit for Push on Duct. Old one started slipping after a bit of use)
See thingiverse.com/thing:77107 for what looks to be a good improvement to my push on Duct.

Yeah I don't think air goes around corners much. It just obstructs your access to the tip. Not sure how your fans will go in series. You can drive them at half speed with M106 S128
Yep, I'll probably print another one also (bulky). I would try to mount the fans in serie (lower voltage), so as not to ask for more power from the onboard regulator.
As for the shape, I was not suggesting to reduce the opening but to round it slightly "around" the nozzle (ie. not a rectangular ie unidirectional flow). Now, the flow could get turbulent and inefficient, dunno.

Print either Nut Mount Duct or Push on Duct
Fan mount holes are made small so you can screw the screws straight into it without a nut too.
Careful cleaning strings around cable guide (It's a bit delicate)
