Universal PC Fan Duct with CAD [Parametric]

Compatible with any case, it can help improve airflow by reducing dead spots and give a slight noise reduction for fans by distancing fans from heatsink or radiators. (Extreme example below)

How to resize the CAD:

First, open Scalable Fan Shroud v2 Parametric with Fusion360.

Parameters
SIZE - Defines fan size for the model. 120-140 recommended.

HEIGHT - Defines total height of the shroud model.

OFFSETs - angles the walls of the exhaust. This is optional for advanced tinkerers.

*Going beyond recommended values kind of works, but it's more like a duct at that point.

You can even scale WITHOUT CAD, you can scale UNIDUCT140.3mf, UNIDUCT120.3mf via slicer - those were the original free fan shroud models from Modcase.com.au

Any questions feel free to message me.
