A case for the iPhone 12 Mini.  It has a cutout for the built in magsafe charger instead of adding a ring.  The buttons are recessed instead of being covered.  I prefer this, but maybe you don't.  Feel free to remix, I included the FreeCAD file.

I've printed this in ASA and PLA, both worked well, but TPU was too loose, so I'm working on a TPU remix.

You might get away without supports, but I got cleaner results on the button holes with auto snug supports.  I also like archamedian chords for the back/bottom, but my wife doesn't.
