air filter for 40mm fan
thingiverse
To minimize fume levels during ABS extrusion, I designed a filter that can be stuffed with active charcoal or other materials of choice. It is secured to a 40mm fan using M3 screws for optimal airflow. Furthermore, an air blower from this link (http://www.thingiverse.com/thing:30721) can be utilized to boost and direct the air flow more efficiently.
