Shopping Cart Unlocker

A project born, and that I want to share, after endless frustrations in looking for the right coin for the shopping cart!
This accessory, which also becomes a convenient keychain, adapts to coin slots with a circumference ranging from 23 to 27 mm.
It is very easy to print and very light: it uses only 2 grams of filament and you can make it in 5 minutes.
