Window Sash Vent Stop
thingiverse
This design fits in 1.875" x 0.285" window sash vent stop slots. The purpose is to provide a small amount of security when the first floor windows are open overnight. I broke the original parts. You can easily purchase replacements; however, I wanted something a little stronger. By printing this piece with no moving parts, I was able to make the body a bit thicker and stronger. It must be removed if you wish to open the window. I am including the .STL file for 3D printing and the FreeCad (FCStd) file, in case you want to make modifications.
