In theory, with parametric design (eg OpenSCAD, Autodesk Inventor, etc) a model could allow you to enter the phone dimensions and it automatically re-calculates the correct geometry.
In practice, experience says doing this (in a robust way) is a lot harder than it sounds. ;)
It's not really that much harder, as long as you know which dimensions you want to be variable from the start. Going back and changing everything after the fact is a massive pain.

Thanks, very nice design and write-up.
