Window Stopper (customizable)

Customizable window stopper that fills the gap exactly. The Freecad file is attached and can be customized via parameters.

The material thickness is deliberately limited so that the window is not damaged if you accidentally try to close it and forget that the stopper is still in place. The chosen thickness makes the stopper flexible so that it neither breaks nor damages the window. I printed it in ABS. However, PLA or PETG should make no difference.
