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)
There are some other types for higher loads, but its not about anchor, its more about shitty drywall cant hold any load. If you want to hang something heavy you need wooden/metal plate in drywall or you need a concrete wall 😜
