Shopping Cart Coin (Removable)

A customizable shopping trolley release key that unlocks the cart and can be removed immediately without getting stuck.    Key Features:  - Fully Parametric: Enter your own text via the OpenScad Customizer. Coin dimensions are pre-configured for a standard 1 Euro coin but can be adjusted for any local currency.  - Engraved Surface: Text is cleanly debossed into the handle to keep the top surface flat, preventing it from jamming inside the lock mechanism.  - Fast and Lightweight: Prints in 8 to 12 minutes using less than 3 grams of filament.  - Support-Free: Flawless bed adhesion with zero supports needed.    Multi-Color Note: The engraved lettering can be easily colored with the paint bucket tool in the slicer for high-contrast, multi-color prints.
