It seems that most of the drywall mounts that I looked for printed in a vertical orientation, which is not good for strength.
For once, I didn’t reverse engineer anything to design this. Lulz.

Update 8/10 - Added dimension sketches, Added .step file, Added a thinner support ring option that will sit more flush (but not completely)
Neat! How much do you figure it can hold up?
It’s probably limited to the thickness of the drywall. All I needed was a lightweight shelf and maybe a picture or two. I would have to test it to get some real numbers.
Not much. If you want to put heavy stuff up, you should use SnapToggles https://www.toggler-uk.com/snaptoggle/
