I saw someone print something similar to this but for a different camera on Instagram, I lost the name so I feel horrible, but it was not my idea. It is an adapter for the lens from an old CVS brand disposable camera to fit into the Sony A7III Body E Mount.

I used the E Mount cap from Icimdengelen and added the little mount for the lens. Behind the lens to the little aperture hole thing, I have that whole thing chamfered so you do not need to add any supports in there, just ask your slicer to put a pause in your print right before that chamfer begins so you can add a dab of glue the lens. You can do this by either adding a pause point, or a color change depending on the slicer and printer. The only places that need supports are the three sticky outy parts for the actual mount system.

It ended up being extremely out of focus, and the lens was too close to the sensor by about a quarter of an inch. There ended up being cropped by either the inner aperture thing, or by something else. Not sure. I will update if I ever get around to messing with it.
