Replicator 2X Cooling Fan Duct

3D model description

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.

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.

3D printing settings

This thing is designed to print at 0.2 layer height, 2 shells, and 15% fill, no raft or support. I had a little trouble with bridging over the ducts. My solution was to turn off bridging and change the solid layer angle to 90 degrees.

Be sure to clean out any "spaghetti" in the air ways.

The chrome fan guards need to be removed. The fan bolts are M3-10.
