140 mm Fan Dust Filter

thingiverse

I needed an air filter for the side panel of my Fractal Design Define R5 case. The designs are SOLID since you can simply print with zero top and bottom layers to showcase the infill pattern. I clean inside my computer pretty regularly and don't want to hinder airflow, so a honeycomb at 40% works really well with a 4mm nozzle. Hotsnotting refrigerator magnets on the corners worked out perfectly. It includes 10mm and 25mm squares for testing infill size. I just wanted to share my results because I was a bit lazy about making the hot glue look nice, though...
