This is a standard window opening limiter. I'm tired of buying them every six months because they often break down. They are usually made of poor injection molded plastic. So I decided to make a model and print it out of normal plastic.I reduced the bolt hole. I used an M3 bolt. The maximum diameter of the mate pin is 6 mm
