A Simple Keyring Tag That Replaces a £1 Coin in a Shopping Trolley. This handy tag can be attached to your keyring and used as a substitute for a £1 coin when using a shopping trolley. It's designed to fit the exact size of a £1 coin, making it compatible with most shopping carts. I've personally tested this tag at Asda, and I'm confident it works there. I also believe it should work at Aldi and Tesco since it's identical in size to a £1 coin. You can use it anywhere that accepts £1 coins as payment for trolley rentals. To avoid any potential issues, I designed this tag with a simple twist-and-pull mechanism. This way, you can easily remove the tag from your keyring when you're done using it. I've included Cura project files for printing one or three tags on an Ultimaker 2 printer. These files will ensure that your printed tags match the design I created.
