If in other questions I just talk about the principles of the device of a new camera, now I have an exact answer to this question. I have already made a prototype of such a shutter. The prototype is made from ready-made gears and parts printed on a 3D printer. The layout serves the purpose of demonstrating the possibility of creating such a simple design and good performance. You can see a video of my layout working here (will open in the new tab)  https://kosmofoto.com/2022/05/ten-dollar-shutter-a-new-mechanical-shutter-for-film-camera-projects/. It should not be assumed that the final version of the shutter will look like this. No, this is just a demonstration of the principles of the shutter.
