This is an adapter for an 80mm fan to a 3 inch dryer duct (aluminum or spring material). I originally made this to adapt to the "Active Carbon and Hepa Filter assembly set" by Donzi (https://www.thingiverse.com/thing:1764408). This is the reason for the two small rubber-band wings on the design. I decided to screw the fan down to the mounting instead of banding the entire thing together but thought the option would be nice for others using the design.
This adapter allows you to feed the output of the charcoal/HEPA filter back into the printer enclosure to retain the heat created by a heated bed. Using a short run of the 3 inch dryer duct and an insulation sleeve to go around the duct will allow for the most efficient usage.
