Shopping Trolley Coin

thingiverse

Here I present a reusable shopping trolley coin/token that can be easily attached to any keychain, making it simple to carry and use. The coin/token is designed based on the dimensions of a 1€ coin, ensuring a secure fit and easy handling. To find the perfect balance between ease of coin removal and sufficient stiffness, I tested multiple prototypes with friends and family. This process allowed me to refine the design, achieving a durable and satisfying "click" when inserting the coin into the holder. Printing the coin/token using PLA and 100% infill takes only 30 minutes, making it an extremely useful gadget for everyday use. When printed in amazing colours, it becomes an interesting birthday or Christmas gift idea. The models are free for non-commercial use, allowing you to freely download and print them without restrictions. If you find the design useful and want to support my continued creation of gadgets that solve everyday problems, please consider contributing to my late-night coffee supply at buymeacoffee.com/aitiolog. If you would like to see the design modified to work with other currencies (e.g., British £1), feel free to message me.
