Dryer Duct/Hose Attachment (4")

We have 3D printers and now a LASER engraver/cutter. To keep the fumes down, we wanted to vent them out of the house (through a window). To do this required adding some ductwork between the window and the engraver's enclosure (which we slapped together from some scrap wood).This is a model of the hose attachment. We are using 4" dryer hose. We couldn't find anything that was quite what we were looking for at the local hardware stores, so I designed this. It attaches directly to the fan.For best results, have the fan at the window end so it *PULLS* the air from inside to the outside.
