Thatcheria Mirabilis Shell Earrings

A small ocean-inspired earrings model, based on the same Thatcheria mirabilis shell design and adapted into a lightweight wearable accessory.

The shape keeps the natural shell feeling, with a cute spiral form and a small hole ready for earring hooks or small jump rings. It looks great in simple white, silk gold, blue, marble, brown, pearl, or even rainbow filament.

The earrings are small, light, and easy to wear. Perfect as a quick gift print, beach-style accessory, or a fun jewelry project for makers.

The model is tuned for easy FDM printing and only needs a few small supports. The supports are placed in a way that makes them easy to remove after printing.
