Everyone who owns a KP3s knows about its noisy fans. So I decided to design a fan duct for two 12v (in series) Noctua fans and added a modular extruder cooler mount.

As you can see on the pictures the holes are made for silicone fan connectors delivered with every Noctua fan. So everything is decoupled.

I use these ultra silent fans

In the file section you'll also find complete step files for remixing this project (please upload your remixes :) )

Printing requires some support structures (only bed touching support).
