Canadian Cart Coin Tool - Double-sided - for keychain

This is a shopping cart coin tool for Canadians. One end works for Loonie's and the other Quarters. Hollow/slotted center for addition to your keychain. 

This design is loosely based on other models, such as https://www.printables.com/model/394782-cart-coin. 

I included two models, one hollow center, the other slotted. They are otherwise the same. Slotted might make a better fidget toy.

The design is flat, no fillet, for ease of printing. This is something I found troublesome from other models.

I printed in PETG for a little flexibility, but any material is probably fine.
