3D model description

As part of my lack enclosure I've designed some exhaust systems to lower temps within the enclosure. This system uses these filters off amazon, unsure of their effectiveness but surely they must do something, right?

This fits a standard 120mm PC fan, try to find one with high static pressure. I personally went with the ARCTIC BioniX P120 for its cheap cost and high static pressure.

Included are the carbon casing files, these two slot together to form a round carbon casing for odor filtration. I've stopped using it due to airflow restriction and the bento box within the enclosure does a good enough job. Print the carbon casing with ~25% infill, zero top shells and zero bottom shells and glue together after printing. If using carbon be sure to use acid-free carbon (I got mine from here).

The shroud on the outer part of the fan isnt needed, I just like it to feel how much air is being pulled through the filter. Regardless, the model can be found here (https://www.printables.com/model/268401-noctua-desk-fan). I have it scaled to fit 120mm and chopped the ends of the ducts off to make it slimmer.
