This a stand for iPhone 12 Pro Max, 13 Pro Max, 14 Pro Max and 15 Pro Max. A long time ago, there was a very simple and usable iPhone stand for aeroplanes or working in a cafe created by a company named MoviePeg. Unfortunately it seems like the company is no more, and I had been looking for an updated version for my iPhone 14 Pro Max.
I printed mine of a Bambu A1 mini with a matte black PLA filament (also from Bambu).
This is a stand I made using Fusion 360. I think it is light, simple and very functional.
Please do not post it on other sites, or sell it commercially as it was originally created by a commercial entity (although now defunct).
