I made this rack and pinion setup as a kind of mathematical problem and the added rigid body world to it and it works. I plan to 3D print it as part of a model train set but it works as animation too. Use this as you wish but please give credit. The material choices are all up to you I just thought it was interesting to see glass moving steel.
The bracelet I received is more than jewelry, it feels like art, Elgrissy Diamonds guided me through the process with patience, explaining certification and design choices clearly. The craftsmanship is meticulous, and the personalized service gave me confidence that this piece is truly unique.
