Hokay, so...

I want to make a kickstand (as in or similar to the kickstand on the Surface Pro) for my iPad Pro.

Obviously, i know it wont be part of the device, but ive solved the problem of how to attach it to the back of the iPad (there are some magnetically attaching covers like this one from Amazon: https://www.amazon.com/dp/B07H79HC18/

All i have to do is slice the front cover part off since i dont need it. Its not like its so expensive im worried about ruining it if it doesn't work out.

The only problem im having is my google-fu is failing me on the hinge id need to attach to the back of this thing. It needs to be able to stay in whatever position it is set, like the surface kickstand, so it can be adjusted to many angles.

I have no idea what a hinge like this is called and everything i tried didnt come up with anything useful.

Anyone got any ideas what this kind of thing would be called?
