I went through a lot of designs to fit a nice 100mm system I have and I really liked that yours had another filter in the line. I don't even run it out of the room, just through an advanced filter box. That makes internal charcoal, exit charcoal and HEPA, then high quality HEPA. Going to be measuring quality of air coming out of it. Using an AC Infinity Cloudline blower, super quiet, and not too hard as to alter the internal temp of the chamber, just keep air always moving through the filters. I think I'm going to make an effort to put stickers over a few of those base holes (like the ones the allow you to wire in a Bento Box). If you could make a similar design but for the right hand electronics vent, I would love to kill two particle/smell exits with one stone. Thanks again for the great design. (sorry this one for some reason wouldn't let me rate it but the design is five stars!)

Excellent build! Works exactly as advertised and cuts down on fan noise a considerable ammount. I designed a gasket for this to make a better seal between the adapter and the printer
