I always forget coins for a shopping cart, but I always have the keys with me. That's why I've designed this simple shopping cart token that works as a coin. It is removable so you just unlock your shopping cart with it and put it back to your pocket.
I've created a lot of variations, but I really recommend the one with a hole - it works as a fidget toy!
I also uploaded an empty one, so you can make your own design. Just don't forget to mention where you got it, or upload it as a remix, I'll greatly appreciate it :)
It's designed to be simple and fast to print, so it doesn't need any supports.
