I designed this because I wanted a fume extractor built into my soldering station. I also wanted to be able to change out the holder to different tools.
The fume extractor is designed to take a 120mm x 120mm fan and a 140mm x 140mm x 10mm filter. I am still experimenting with the material I am using for the filter.
The clips are meant to slide down from the top and just friction fit over the filter material to keep it from falling out. I printed two, I think you could get away with one as the fan will help keep the filter material in place. I suppose one could just use some sort of double sided tape as well and not print any clips.
I have included some holder tools and will add more as I need/design them.
