Fan duct for a Creality family 3D printers, like Ender 3
Lightweight and compact. Printed with minimal supports (tree support might be a good idea).
This version it`s designed for a E3DV6 (or clone) hotend only. NOT for a stock Creality hotend. Also, because of the lack of height adjust, yours hotend (from top of the radiator, to the end of the nozzle) must be =>62mm long.
