One of the problems I'd found with the recommended fan shroud is that it only cools from one side of the extruder - after printing and installing this I'm getting a much more uniform print (in PLA at least, I don't use fans with ABS or Nylon) and less stringing.

The model is printed in Black ABS at 235c on Kaptop tape, gluestick and used a heavy brim of 5mm. Available at Thingiverse here.
