Mk7 fan duct

thingiverse

A dualstruder-compatible duct that diverts some air from the extruder fan so that it blows on the nozzle. This should help plastic cool faster, which again should lead to better bridges. Instructions (optional) Use a 3mm tap to thread the top holes disassemble the Mk7 extruder, and re-assemble using this duct instead of the fan fasten the fan to the duct using two M3x16 bolts print! (hey, Thingyverse, why don't my tags above work?)
