The removable shopping cart coin is an essential tool for your everyday shopping trips. This cleverly designed keychain not only holds your keys but also doubles as an opener for shopping carts. With its sleek and modern design, this coin is perfect for anyone looking to simplify their shopping experience. The removable shopping cart coin allows you to unlock a shopping cart and remove the coin afterward, making it both practical and versatile.

Printing Instructions:

Printing the removable shopping cart coin is easy and straightforward.
No special configurations are needed; it can be printed using standard 3D printing profiles.
While a layer height of 0.2 mm is acceptable, we recommend a finer layer height of 0.15 mm for better detail.
We also recommend setting the infill to 100% to ensure robust prints.
For materials, PLA or PETG is recommended for their ease of use and durability.

Tool Objective:

The objective is simple: unlock shopping carts with ease and convenience, especially when you don’t have coins on hand. The removable shopping cart coin is designed to be inserted into the shopping cart lock and then removed once the cart is unlocked. This makes it a reusable and handy tool for quick and hassle-free shopping trips. Its durable construction ensures it can withstand repeated use, making it a cost-effective solution for your shopping needs and avoiding the inconvenience of having to find and insert coins, only to retrieve them at the end.

The head of the coin is sized like a 1€ coin, ensuring compatibility with all shopping carts that accept euro coins. The diameter of a 1€ coin is 23.25 mm, and this removable coin should work with any shopping cart mechanism that accepts coins of similar size. While it should also function with coins from other countries, we invite users to leave reviews and share which other coins they’ve successfully used with the coin.

Did You Know?

The concept of a shopping cart was invented by Sylvan Goldman in 1937 to enhance the shopping experience in supermarkets. Since then, various tools and accessories have been developed to improve the convenience of using shopping carts, including cart openers that save you from carrying loose coins . Interestingly, shopping carts can also be opened simply with the back of a round key.
