75mm Exhaust Diffusers

I made these while building a filter box for my Creality Falcon 2 22W's 75mm exhaust hose from the standard Creality enclosure. I used an old IKEA air purifier and built a box to which I mounted a 75mm flange (https://www.thingiverse.com/thing:6967924) which ensured all of the exhaust goodness is directed at the filter.

What I didn't want though is a straight pipe of exhaust hitting the filter in the middle and wasting the surrounds, so I made these diffusers that get mounted back-to-back with the flange to spread the intake out a bit and allowing the filter to be used evenly.
