Basement Vent Duct

If you're in the basement and 3D printing or doing laser engraving, you'll need a way to vent out. I've created a duct adapter that will allow you to connect your 4inch vent pipe to the small window openings that the basement allows. You will need screws and some glue to attach the 2 sections. I've been using this for 6 months and it has worked great.
