StopVOC Redux

A while back I had made a great big octagonal thing I called the StopVOC to act as a dedicated VOC filter by means of using a 120mm fan to push air through a big container full of activated charcoal. It worked, but it was very big and honestly didn't work as well as I wanted - the filter media was mostly unused as the air it pushed just went around it inside the container - path of least resistance and whatnot. I generally just leave this behind my printer, pulling air away from the chamber fan exhaust port. I re-made it just as a plain square this time, but with a conical internal design that helped to ensure when filled air would have to go through the filter media. All the normal “think like a printer” considerations during design make for something that actually prints really well - I've made three of these so far without an issue. There are three printable pieces - the body, the lid, and an optional gasket (TPE/TPU). You'll need a 120mm fan with a high static pressure,
