iPhone 12 Mini Minimal Back Skin

I have very simple requirements for my phone that are not being fulfilled by the current smartphone market: small phone, no camera bump, and still receives security updates. The closest phone (android or apple) that I could find in 2025 is the iPhone 12 or 13 mini - which sadly have freaking asymmetrical camera bumps. I like to use my phone flat on a surface and the wobbling caused by the camera bump drives me nuts. I also like to live dangerously without a case.

This print is thin back skin for the iPhone 12 mini attached with double sided tape (I used https://a.co/d/igRmOvK). I printed it in clear TPU (https://a.co/d/dJh40fQ). The skin's thickness is almost exactly the height of the camera bump. There is also a small chin at the bottom that keeps the phone level when sitting flat on a surface. The bumps ramp down to a single layer and the layer lines in the ramp region act as extra grippy sections.

I printed this on a Bambu Lab X1C. Settings that deviate from Bambu's TPU defaults
