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 has a freaking asymmetrical camera bump. 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 a simple visor attached to the back of the phone with double sided tape (I used https://a.co/d/igRmOvK). I printed it in clear TPU (https://a.co/d/dJh40fQ). Both a top and optional bottom part are included if you want it to sit really flat. This is the lowest bulk solution I could think of.

Update: Uploaded a version that covers the entire back. I used 0.15mm layer height and Hilbert curve for the top, bottom, and 100% solid infill. The texture makes the phone much more grippy.
