Customizable Foldable Phone Stand With Keyring

I was looking for a configurable mobile phone stand that would work in both portrait and landscape, and attach to a keyring. I liked https://www.thingiverse.com/thing:4521613/files but I also liked the simplicity of https://www.thingiverse.com/thing:1666131 , even though it didn't have a keyring hole.

So I modified it to include a keyring hole, and also incorporated the same kind of idea as from https://www.thingiverse.com/thing:1884370 to give the stand a smaller front lip for better viewing of the screen . I've also incorporated these parameters into the .scad file for you to configure.

I tried printing this flat (lying down), with a support structure only really required in the gap between the two halves, and it worked ok. Maybe printing vertically would be better (not sure about the hinge) - but I haven't tried that.
