HEPA Air Filter Scrubber Tower

This is an air treatment system for the interior of a 3D printer enclosure. This design is intended to: * capture particulates (HEPA filter), * absorb moisture (desiccant granules), * adsorb volatile organic compounds (activated charcoal) that are byproducts of printing with filament such as ABS. Inspired by the work of @RJ_Make and @jmillerfo, this is a remix of their designs to make this vertical stack filter tower. My goal in this remix is to improve filtration and minimize the footprint of the air filter within my enclosure. I have modified two of jmillerfo's models, and provided new models for all other parts of this Thing. However, I am completely reusing the purchased parts recommendations (except for the screws) from @jmillerfo. I notice that @jmillerfo continues to update his parts list, so check his thing before making any purchases. ** Updated Aug-2022 to add a stand-less wall mount option, and a HEPA chamber tight seal option. **
