This adapter allows you to use a Moment bayonet lens on your iPhone 15 Pro Max. It may also work for other models; I do not have any other models to test for fitment. I am including the Fusion 360 file here so you can adapt if needed.

The adapter is press fit to the lenses. For additional support, use a case around your phone. I found the FineWoven case provides a very snug fit, but it is not necessary.

I printed with a .25mm nozzle owing to the thinness of the model. Resin printing may also be a good idea.

I've included four model files, depending on whether you want the telephoto ring or not, and your preference on thickness. The thinner models require support when printing; thicker models do not.
