"The Stinkinator" Exhaust Port for 40mm Fan

cults3d

This is a simple exhaust port to help get rid of ABS fumes and particles. It's intended to go inside or outside of a 3D printer enclosure. It utilizes activated carbon pellets (easily available at a pet-store) and any HEPA filter material. I've even used a doctor/nurse face mask in a pinch. My enclosure is in my garage which double as a wood shop, so I want to keep dust from getting into my enclosure also. Basically, fill the "port" with activated charcoal pellets, then put the cap on. If you are placing the port on the outside of the enclosure you will want to sandwich a piece of HEPA filter between the cap and the port to make sure dust doesn't get into the charcoal chamber. Then sandwich the whole assembly to a 12V 40mm PC fan and continue the bolts through the enclosure wall. If you are installing the port on the inside of the enclosure then you will want to put the HEPA filter in between the interior wall and the fan to make sure no dust gets into the enclosure.
