140 mm Fan Dust Filter

thingiverse

I wanted a dust filter for the side panel of my Fractal Design Define R5 case. The files are SOLID since you can simply print with zero top and bottom layers to show the infill pattern. I dust inside my computer pretty regularly and don't want to compromise airflow, so honeycomb at 40% works pretty well with a 4mm nozzle. Hotsnotting refrigerator magnets on the corners worked perfectly. Includes 10mm and 25mm squares for testing infill size. Just thought I'd share my results :) I was a bit lazy about making the hot glue look nice though...
