Fan Duct for Raise 3D N2/N2+, Single Extruder

Currently I don't use the second extruder of my dual extruder N2. Because I needed better control over object cooling, I designed this fan duct. It is mounted in the same way as the right fan in a dual extruder setup.

There is no support needed for printing if you lay it on the surface where the fan is mounted. I printed mine with eSun ePC and 100% infill.
