This is a small butt hinge that I have not yet printed but have designed as a redesign as some commercially available butt hinges. It is made for boxes mostly, But if you did print it with metal filament you could be able to use it on a door or gate. If you wanted to make it stronger you could replace the pin with a 2 mm metal pin. You may have to sand down the parts to fit and if you want to make it smoother you could oil it.
