✨ Overview

This elegant and refined keychain design was carefully crafted from scratch by Printalys to achieve the smoothest spiral lines, a graceful silhouette, and maximum everyday usability.
It includes 1 base body + 7 interchangeable caps, each created to fit nearly all common keychain attachment styles. The caps are not thin ornamental pieces — they are intentionally designed with durable connection points for long-term use.

Each part has been digitally organized and clearly named inside the STL package, ensuring a seamless experience from download to print.
This model has been designed, tested, iterated, and optimized exclusively by Printalys. Therefore, redistribution, reselling, or creating same models for sale is strictly prohibited.
