I had been looking for a dual purpose E3D and Part Fan for some time, but all of the designs I found required either a specific printer, or specific extruder. I decided to combine both designs into one and this is what I got. I am only to be credited for splicing two models as I was being extremely lazy to come up with my own part fan. The two original models that I used are: Original E3D Shroud : http://www.thingiverse.com/thing:114036 Original Part Fan : http://www.thingiverse.com/thing:252545 I have made two STL files. One with, the other without spports. I found that Cura used supports that were so dense they broke the part. Print Settings: 0.2 mm Layer Height 20 % Infill EDIT Minor clipping was needed to prevent the fins near the nozzle from touching the nozzle.
