120mm PC Fan Filter

thingiverse

Dust filter for 120mm PC case fans. I placed these between the my PC's intake fans and the case itself to help keep the cat hair at bay. It is very thin, so you shouldn't need longer screws or anything I've included the OpenSCAD file which should be pretty easy to modify to fit other fan sizes, but I can also upload STL's by request! A couple of things to note: - When slicing, at least in Cura, you will need to enable the "print thin walls" setting or it will only print the frame. Hit the preview button to make sure everything is there before saving. - You can use fan_filter_test.stl to make sure your slicer/printer are handling the single strands properly before attempting to print the whole thing. - I have screen_width set to .4mm because that is the nozzle diameter on my Ender 3. If you are using a different nozzle size, I would recommend adjusting this. - Because screen is made up of so many tiny strands, this takes quite a long time (several minutes) to render in OpenSCAD. Be patient, it probably didn't actually freeze.
