AC Infinity Fan to 4in Dryer Duct

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4574406.

I built an enclosure for my (6) 3d printers, but I didn't have an area to vent hot air without being blocked. I had extra dryer ducting laying around in the garage, so I designed this model to vent the air out.

There are (2) different versions, one with a grill and one without. No Supports, I try to design models that do not require them.
