Thatcheria Mirabilis Shell Keychain

Meet a tiny shell with a big personality 🐚 This model is based on the beautiful Thatcheria mirabilis shell, originally sourced from the free Smithsonian 3D collection. I turned the shell shape into a small printable holder/keychain charm while keeping its natural, realistic shell look. It is small, lightweight, and fun to print. The organic spiral shape gives it a very real seashell feeling, especially when printed in white, marble, silk, translucent, or warm orange filament. Great for: Keychain charm Bag accessory Small decorative shell Gift print Ocean / beach themed collection Tiny useful 3D print The model includes a small hole for a ball chain or keyring. It prints with a little tree support, easy to remove. Source / Credit Base shell model by the Smithsonian 3D model: Thatcheria mirabilis.
