Tilt Window Fence *No Screws, No Glue*

Edit: Sorry for the crappy Pictures! I'll try to take some better ones soon.

Since i have two little kittens i am worried they'd try to jump out of tilted windows or balcony doors, get stuck and might hurt themselves. Therefore i designed this conic fencing you can simply slot into the opening.
There are three parts which can be connected with zip ties.

For a Balcony Door i used all three of them, fro a window only two.

Fell free to contact me and share your prints :D
