USE AT YOUR OWN RISK
This is a model that holds a 98.6mm x 98.60mm x 31mm air filter commonly found on amazon and also uses 2 40x40x20 12volt fans to pull air through the filter. This filter does work very well after using for a month but is not super powerful but does what i need it to and reduces a bunch of smell in my opinion. I DO NOT HAVE proper filtration equipment to test how well it works and at what levels USE AT YOUR OWN RISK. just something that works for me in a enclosure when used with glow in the dark filament. Has not been tested on any abs asa tpu filaments I only use it for pla and petg if anyone is experienced with those filaments and would provide feedback i would greatly appreciate it thanks.
I did use the fan section piece from the bento box v2 version but modified it significantly to create another model.
