NEW AND IMPROVED!
Revision 4 has modified outlets which direct air flow in a more downward direction, and less toward the nozzles. Also, STEP & IGES file formats (R4) are now posted. Made to fit a third 40mm fan for active cooling. The reason I designed this is because I wanted to get air all around the print. Having air coming from just the front was not working well for my needs. Check out some great before and after pictures here: http://www.thingiverse.com/make:75635 This design hugs a little closer to the extruder carriage than some other versions. This keeps it away from the front door hinge bolts! Helpful for PLA and ABS prints. Find the NEW Flash Forge version here: http://www.thingiverse.com/thing:259688
