Anet E12 extruder fan vent

thingiverse

Having some test prints on my Anet E12, I discovered warping effects on the opposite side of where the fan was blowing to the nozzle. Not finding any radial vents in Thingiverse for the custom fan, I came up with one myself. Starting with reusing a ring shape (step file) from the ender version, I soon realized there should be more air and a second mounting point to it, as seen in the stl. This is my third iteration of nozzle cooling for the E12, and I've already done a few printing days with this one, along with some additional tests. I would appreciate any comments on this design as a starting point for continued improvement on E12 nozzle cooling.
