Window Stopper

The shape helps to keep the stopper in place, even if the window is moving due to wind. It can be used symmetrically.I printed it in Armadillo TPU (https://ninjatek.com/shop/armadillo), a very hard TPU, but I think any material can be used.To prevent damages on your window, while trying to close it with the stopper inside (this will happen sometimes at the beginning 😉), I recommend to print it in any kind of TPU.It is 4cm wide at the thinnest pointUPDATE:I made the outer wall a little bit thicker, so that when printed in TPU, it won't squeeze together but rather slide a little bit better up and down (hopefully)
