Description
This 3D-printed keychain is designed as a threaded "shopping coin" that fits and unlocks two different types of shopping carts using a single model. The clever screw-like design allows you to easily insert and twist it into place, making it a practical and reusable alternative to traditional coins. Compact, functional, and always at hand – perfect for your keyring.
