Geeetech A10M 4020 Blower Fan Duct

thingiverse

This is not the normal fan for the A10M, but it did come stock out of the box, so maybe it's the new one, or the old one...whatever it's a 4020 blower. I felt the stock one was a bit restrictive and after going down the rabbit hole of researching complicated ring ducts, exhaust angles and pressure gradients, it seems like you can get good results in two ways, either with the ideally designed ring duct, or buy throwing large CFM at the problem and just running a wide open duct to flow as much air as possible. I did that, and went with heresy and crazy glued it to the fan just to add to my sins. 3mf, step, and f3d files here as well.
