Summary

This is a no piercing earring hook. It goes behind the ear and hangs on it. The hook has 2 holes for pendants. Supports are required only for the perpendicular loop and some printers probably don't need supports at all. For me the loop prints better if supports are on.

I used skin colour PETG here but any filament should work fine. For the second earring just mirror the model along the X-axis.

This particular shape is designed for my ears and might or might not work for you. Sorry if it doesn't fit. stretching it along X or Y axis or both a bit might work if you have smaller or larger ears.

ADDED: That visible loop was a bit annoying, so I added an example of how to hide it with a little mushroom insert. Mushroom pendant and the insert can be downloaded here: https://www.thingiverse.com/thing:6719424
