Description
This is the ultimate solution for supermarket shopping carts! While many 3D printed tokens work on standard push-slot carts, they often fail or get stuck in carts that use a sliding drawer or door mechanism.
This Universal "Unclip" variant solves that problem with a smart two-part modular design.
How it works: The design consists of two separate parts that snap together securely:
The Coin, which mimics a standard Euro coin (€1/€2 size).
The Clip Handle, which attaches to your keyring.
For standard carts, keep them snapped together and use it like a normal tool. For carts with a drawer mechanism, simply slide the assembly in. If the mechanism requires the coin to drop, the two parts are designed to separate, allowing the coin to do its job without the handle getting in the way.
Key Features:
Universal Compatibility: Works on virtually all cart types, including tricky drawer slots.
Secure Snap-Fit: The parts stay together on your keyring but separate when needed.
Keyring Ready: Always have it handy.
Two-Piece Print: Prints quickly and easily without supports.
