-The keychain is based on a Tinkercad design of [IronGears10](https://www.tinkercad.com/things/iPPfRoUBe1q-3d-pcb-layout) licensed based on CC BY-SA 3.0. There are some modification done. Final Tinkercad is shared [here](https://www.tinkercad.com/things/lqzVt5o8N8M-vanier-floss-day-swag-3d), and you can find the final design in form of the Prusa Slicer project (`3mf`) in this repo.
