When I first declared my major as mechanical engineering, one of my best friends gifted me a mechanical gear necklace. It was made of simple balsa wood and the gears were connected in such a way that they rotated altering the shape of the necklace. I loved the necklace, but the fragile wood soon broke and it has long since been thrown away. The design was similar to the image below. This design allows the user to ensure all the gears mesh and turn. This could be a perfect design to prototype with the laser cutter.

This is sweet Katie! I dont know if you’ve found a source to acquire small brass/metal gears but I’ve seen some cool stuff on etsy.com that may interest you. Theyre cheap too! Best of luck
Wow, I love the look of that jewelry. I agree that mixing up the different metal and different size teeth gives it added visual appeal. I like the look of metal, but using a 3D printer to make it could be interesting too. Good luck!
