Simple remix of “KLEMCO V6 Hotend Mount Fan Duct” by Noah Works.
The air outlet was moved to the center to blow air evenly on the nozzle of the hotend.
Mounted on Ender 3V2 with V6 clone.
Print on the side with the mounting bracket touching buildplate. Use support only below the air outlet, otherwise the support will be impossible to remove from the inside of the duct.
I recommend using filament with higher melting point than PLA, I've used PETG.
40% infill is more than enough.
