I always lose my shopping cart coins, so I created my own. And since it's the holiday season, here are five different christmas themed coins. That way, when you do your groceries for the holidays, you are sure that your shopping cart coin is appropriately themed!
This coin is based on Dutch supermarket cart coins, but I am pretty sure you can use them across Europe, and quite likely beyond that as well. I have included the step files, just in case the coins you need for your shopping carts are a slightly different size.
I have printed these both with a 0.4mm and a 0.2mm nozzle. Obviously, the details are even better on a 0.2mm nozzle, but I think they look pretty good with a 0.4mm too. The included picture is with the 0.4mm.
Enjoy, and happy holidays!
