EDIT: I would no longer use this. Blower fans are much better for cooling PLA as they support a higher pressure differential. Try my new design.

This is an improved PLA cooling fan mount for the kossel clear fan mount. It accepts 2 X 40 mm fans for cooling the PLA, and one 30 mm fan for cooling the extruder. If you get the thin 40 mm fans you can mount them to the inside. In this configuration the fans have almost no impact on your printable area. Also, the other designs with the 40 mm fans on the same side always seemed to not cool the pla as well if the corner was on the opposite sides. Since this design has the fans 180 degrees apart, i am hoping it works better. Just starting to try it now.
I recommend this fan duct for the extruder, even though the nut area seems to always be too small when i print it. I just drill it out and or ABS glue the nut in.
