1€ Trolley Coins - Filament friendly

Intro

Never worry about forgetting your coin again! This 3D-printable 1 € trolley coin lets you unlock supermarket shopping carts without needing real money. It’s designed to be easy to print and uses less filament than most other trolley token designs, making it ideal for quick everyday prints and filament-efficient projects. 

Whether you keep it on your keychain, in your car, or in your bag, this handy token makes shopping more convenient — especially if you rarely carry cash.

To get this design, there are two versions: One, where you can apply your own favorite settings, and another one with a preset honeycomb grid.
