Simple Keychain 1.0

I have designed a 3D printable keychain model, customizable in various colors, with a compact size of 15x15x40 mm. This keychain serves as an organized key management system, allowing you to assign different colors to each key for easy identification. By printing in multiple colors, you can create a color-coded grid, ensuring you always know which key corresponds to which lock. The model is practical, accessible, and can be printed in under 30 minutes, perfect for keeping your keys neatly organized.
