I needed a case for a new iPhone, and 3d party cases weren't ready yet. I knocked this one out surprisingly quickly (a surprise to me, as much as anyone else), and it fit so well that I decided to share it.

No photos, yet, but it printed very well in PLA at .16 layer height. Added some screenshots

Do with it what you will.

UPDATE: The case felt kind of chunky to me. The new "Thin" version minimizes the thickness. The "Protector" file adds some extra protection for the lenses, which would be exposed without it. Just glue it on after printing. (It is separate to avoid supports.)

The "Adjustable.zip" is a collection of parts that could be edited with TinkerCAD. Slice down the face and back with a slab shaped hole, position the parts, then group the parts together before exporting for print.

There is probably a better way to do it, but I have yet to learn what that is.
