Trolley Coin (Singapore)

thingiverse

Supermarket trolleys in Singapore demand a coin to release them from their parking dock. The coin is returned once you secure the cart back at the station. Occasionally, the required coin cannot be found, prompting a need for a coin substitute. Typically, two distinct sizes of coins are used, one slightly larger than the other.
