shopping cart euro coin key chain

Model Overview & Print Notes

Summary Print and keep one of these in your keychain. When at your favorite supermarket, use this to release a shopping cart/trolley. Pull it back and put again in your pocket. Happy shopping ! This is my first 3d printer design back in 2014. The idea of course is not mine, I think there used to be dummy coins for shopping carts like these long before 3d printers were invented. This design is from scratch. I simply measured a euro coin and placed a tag for your keychain. This is my favorite print to hand out to friends and loved ones. It prints fast with no special settings. I have printed in PLA, ABS, PETG, all work great.
