I recently changed my BMG-E3D V6 hotend to a BMG Aero/Mellow NF-Wind style extruder, and realized there's no dual fan duct designed online; so here you go, a dual fan lightweight fan duct for it. This is a fast design, no expect some glitches, but works like a charm!
You shouldn't need supports if your printer is capable of doing ~2cm bridges. I used PETG, but any filament should work.
