IGES files NOW AVAILABLE! STEP files NOW AVAILABLE! This was a Mid-Coast to West-Coast collaborative effort with pcenginefx! (http://www.thingiverse.com/pcenginefx/designs). I did the CAD and he did the testing and photography. This is a remix of http://www.thingiverse.com/thing:228055 for REP2X. Made to fit a third 40mm fan for active cooling. The reason I originally designed this for our Replicator2X, is because I wanted to get air all around the nozzle while printing. Having air coming from just the front was not working well for my needs. Now Flash Forge owners can enjoy the same benefits! This design hugs a little closer to the extruder carriage than some other versions. Helpful for PLA and ABS prints.
