Clip for window panel

thingiverse

I created clips to secure an acrylic panel from inside the window for portable AC units. A single 3-4mm hex bolt inserted through a hole in the acrylic panel will hold it firmly in place. When tightened loosely, the clip holds securely and loosening allows for easy removal of the panel. You can use these clips with various materials such as plywood or polycarbonate but I preferred acrylic mainly because it's an affordable transparent material.
