Inverted HEPA Air Filter Scrubber Tower

thingiverse

Here is the text with modifications: A minor tweak was made to the Nozzle section of the Filter Tower to allow it to be suspended from the top panel of the printer enclosure. My enclosure is constructed from 1/2 inch plywood, so that's what I designed it to accommodate. A 13mm extension was added to the narrow end of the Nozzle, and an additional locking tab was included to help support the weight. Also incorporated is a cage that goes on the outside of the enclosure to not only secure the nozzle in place but also confine a ping pong ball to serve as a backflow prevention valve. I have yet to print any of this out to put it to the test
