120mm Fan filter frame

A simple frame for 120mm fan dust filters.

I designed it for my Ikea Eket cabinet airflow mod and my custom ATX case.

You can use an aftermarket 120mm magnetic dust filter such as these or print the supplied filter yourself with pause at the last layer for 5x5x1 mm magnets insertion. by changing the infill value you can change the mesh density of the filter

I personally use my filter design for exhaust fans with a 15% infill value and the aftermarket one for intake fans
