These parts adapt a blower type fan for use on the front of the machine. The shroud snaps into place and was printed with PET while the rest was done in PLA.
NEW VERSION: HEX
** Warning - On long builds I've melted this shroud pretty badly where its close to the heater block. You might want to put some aluminum foil tape or kapton on the inside to prevent this if you are going to use it. I'm working on a redesign. Thanks for your interest. ***
I've redesigned the shroud to have six outlets near the nozzle but pointing down only onto the extrudate. These are spaced apart so as to allow the nozzle to be visible from several angles as well. Plus it looks cool. No pun intended.
This is the fan I used:
Don't print the shroud with supports.
The holes are a little small and will need to be drilled out for M3 and M4 screws.

The shroud is an adaptation of a design by delukart.
Wanhao Duplicator i3 (Pruisa i3)
0.1 - 0.18mm
The area of the shroud that needs supporting is the horizontal upper section of the female socket that mates up to the elbow and the arches within. Do not autosupport! Your software may put supports inside the cooler which cannot be removed.
The only area of the elbow that needs to be supported is the horizontal underside of the male part of the socket and the arches within.
I suggest PET for the shroud and use cooling (regardless of material) for at least the top half of the print for the nozzles.
Once supports are cleaned out, superglue the elbow to the shroud. It should be a fairly tight fit.
Depending on how your heating block is oriented, a corner may rest close enough to the shroud to melt it locally. I suggest taping the inside of the shroud with kapton or aluminum tape just to be safe.
The holes are a little small in the mounting bracket and will need to be drilled out for M3 and M4 screws. The screw on the left side goes in from the underside.
Once supports are removed, a little filing or scraping may be needed to get the elbow to fully seat into the shroud.
