Magnetic window exhaust outlet plate 4 inch

I needed an exhaust system for my DIY airbrush booth and loved the Resin printer exhaust system designed by @OnceinaSixSide. But where they designed a quick connect system at the printerside and a fixed system at the window end, I wanted a fixed hose on my spray booth and a quick connect / disconnect side at my window so I didn't need to leave a panel in the window. So I merged the wall plate and the magnetic printer side in the original design to make this magnetic hose attachment plate for the window panel. (photos added 04-27-23)
