UPDATE 20. Dec 2023: Added US Quarter and Toonie coin size.
I improved the shopping cart key by @Inhar (https://www.thingiverse.com/thing:6296753).
The changes include a wider hole (6 mm) for larger keychain rings and a widened grip to make handling a bit easier. The rest is exactly the same as his original.
