I needed to vent a new laser engraver and wanted to set something up that could slide into my basement window and have a vent for casual use to open or close if the weather was being nasty. I added ΒΌ" weather stripping around all edges.
The remaining parts for the valve etc I didn't modify although if I was printing another I might beef them up a bit as the shaft feels a little wimpy.
I used the cut tool in Prusaslicer to make it fit with dowels with glue and a strip of duct tape to stop any leaks.
I also made a coupler from the vent body, I wanted that ridge on it so the zip ties would be on there and they couldn't come apart.
The author remixed this model.
I added the duct housing of the model to a rectangular panel to fit in the grove of a basement window in my house.
