Some of my family likes popsocket, and others like magsafe. So that I can mount my magsafe phone in my kid's car that has a popsocket mount, I made a quick adapter.
Purchase a magsafe magnetic ring sticker and apply it to the large side. Clip the cone side into your popsocket mount, and stick your phone onto the magnet. It obviously won't charge, but still mounts securely. Test the fit on your mount before sticking the magnet on.
Print using PETG if you can (to handle the heat in a car), but PLA seems to be holding up OK as well. No supports needed.
