Laser exhaust window vent

A window vent panel that lets a laser engraver's exhaust hose vent through a sliding window gap. A 75 mm hose socket sits in the centre piece, and the rest of the panel is made of identical filler pieces that glue together with angled joints, so every piece fits on a normal print bed. You can change the window width and height, the hose size, the collar and the number of pieces.
