O—KEY keychain

This keychain was 3D printed, and it's more than just a keychain. It's also a connector that makes it super easy to attach, hang, and organize whatever you need, wherever you want. It's a cool-looking keychain that makes it a breeze to find your keys. You can connect it to other keychains or to each other. It can also be used as a hanger for towels or other textiles that are tricky to hang on your own.
We came up with this idea because we had some PLA material left over. We couldn't use it for larger projects anymore, but we didn't want to waste it.
So, we thought of this clever little keychain as a way to keep things zero waste!
