Window Trap

thingiverse

You can efficiently ventilate your entire apartment by keeping windows open as far as possible. One of the key challenges was developing a device that could be easily attached to the window sill using double-sided tape, allowing for effortless removal without leaving any marks. To use this system, simply swing the clamp upwards when you want to open the window, and you're good to go! When it's time to close the window, just lay the clamp flat on the sill. By swapping the holders, you can even flip the clamp in the opposite direction for added versatility.
