Shopping Trolley Coin

thingiverse

Here I present the reusable shopping trolley coin/token with a holder that can be easily attached to any keychain. The coin and holder are modelled based on the dimensions of 1€ coin. Multiple prototypes were tested by friends and family to find the perfect balance between easy coin removal and stiffness that gives needed durability and satisfying "click" when the coin is inserted in the holder. https://youtu.be/i6t4SGm8g2E Printing with PLA and 100% infill takes 30 minutes. It is an extremely useful gadget for everyday use. Printed in amazing colours is an interesting birthday or Christmas gift. The models are free for non-commercial use. If you find the design useful and would like to support the creation of other gadgets that solve everyday problems, then please contribute to my late-night coffee supply. https://www.buymeacoffee.com/aitiolog Message me if you would like to see the design modified to work with other currencies (e.g. British £1).
