Geneva Mechanism

This is a simple, fully working Geneva mechanism that’s fun to print and satisfying to watch in motion. As the drive wheel spins, the Geneva wheel moves forward one step at a time and then locks in place before the next turn. It’s a great example of how smooth rotation can be turned into precise, controlled steps.The parts fit together easily and the mechanism runs smoothly right off the printer. It works well as a hands-on learning piece, a mechanical desk toy, or just something cool to show how classic mechanisms actually work.
