Shopping Cart Key

Simple yet very useful shopping cart key. I've already printed a lot of them for my family and friends. You no longer need to carry coins to take your cart ;).
The key is as big as a normal key, just add it on the ring.
Push the key straight into the cart, unlock it and then pull sideways.

There is also very light version of this key here - https://www.printables.com/model/208495-shopping-cart-key-light .
