Window Exhaust Ducting Set

These slide into the window frame to exhaust fumes from a 4" dries duct outside of the house.

This window duct system was designed to fit the windows in my house (build in USA in 1997). It may take a little scaling or modification to fit your window well. It is best to print them with something that can take UV exposure and water (not PLA). It also best to use sealing foam or caulk to seal around them to keep bugs or outside air, outside. In my case, my window frame is not completely flat, so I needed to use 2 layers of foam to get the window to shut all the way across.
