Summary

UPDATE: I've redesigned this to include a damper to restrict airflow to a particular extruder.

That version is significantly more useful.

I really liked the design of the active cooling fan duct from thruit00
(http://www.thingiverse.com/thing:537918) primarily because it gets cooling from multiple directions for both extruder head. This seemed to me to be important in a number of cases. However, I wanted a way to use the existing side blower fan on my
2016 FlashForge Creator Pro. Getting a few scraps from http://www.thingiverse.com/thing:1658816 to help figure out how to mount the duct at the fan, I came up with this approach.

Definitely a work in progress. The dimensions are good, but I constructed this in Blender and there are a number of things to improve. First, it is difficult to print the duct. I printed it upside down (relative to installation) with supports underneath for leveling, but this led to problems with bridging on the top. Clearly it would bridge much better if the duct was made flat without the irregular sloping. Second, there is decent airflow, but I haven't been able to measure it. It could probably be improved by taking out the 90 degree bend where it meets to the backing plate. Any other suggestions are welcome and please remix if this is useful for you.
