Hi Fellow Creators, 

I wanted to upgrade my old Ender 3 Pro with Dragonfly Hotend BMS. There was no appropriate Fan Duct so I create one, and now I'm sharing it with you. 

Dragonfly Hotend is low, and take a lot of space, so the fan is thin and directed directly over the hotend (very close to the surface). 

 

You can print it without support, but remember to “flat it” (tilt it little so that it will touch the surface at the bottom of the fan.

PLA works just fine (no melting issues).
