Air filtration system using cardboard box and automotive HEPA filter

thingiverse

I made it to collect dust and tiny particles from the 3D Printing and Airbrush painting stations. To cut down on 3D printing time and money, I used a cardboard box for an Automotive battery, automotive HEPA cabin filter. The chamber separator (thin_wall.stl) is optional. In my case, when I turn on the blower motor of the 3D Printing station, air blows out to the blower motor intake port in the Airbrush painting station, and vice versa. When I have time, I'll upload a clean OpenSCAD file that contains only codes for the parts of the air filtration system.
