Window-clamp for mobile AC exhaust mount

A simple clamp or wedge for mounting a wooden board or Plexiglass sheet into a window frame without damaging it. I'm using this small clamp to fix a plexisglass sheet in my sleeping-room-windows and mount the AC exhaust directly in this plexiglass. The window itself stays open all the time The window-frame is sealed with the plexiglass. The window shutters still work. When I turn on the air conditioner, I just raise the shutter a little bit to expose the exhaust vent.

Printing: print without any supports in PETG - 15% infill is sufficient.

Post printing: Insert a M6-hex-nut in the larger piece and screw in a M6-bolt, pressing the smaller part towards the wooden boad or plexiglas while the larger part fits the window-frame. This will hold the wooden board or plexiglass at its place. Don't overtighten the single clamps - better increase the amount of clamps to gain a tighter fit.
