Fan duct for Ender 3 Max Neo

Behold my poorly designed model made in Fusion 360 with my very basic skills.

For those who want to silence their Ender 3 Max Neo like me. It is designed for two Noctua fans sized 40x40x20mm. It is necessery to use two different DC-DC convertors (LM2596) for each fan as original voltage is 24V. I used one of those convertors to supply only hot end nozzle fan because it is needed to change speed as needed. Second one I used to connect fans at hot end's heat spreader, motherboard and PSU, where I used conversion STL's to 92x16mm Noctuas. Those fans are always on and not even at 12V but less to be even more silent.

To install, click this model over hot end into position and secure with one small propper wood-type screw.
