Camshaft spring mechanism

myminifactory

I designed a camshaft spring mechanism as a fun project, demonstrating a back-and-forth motion where slow forward movement is swiftly countered by rapid backward motion, all while maintaining a consistent rotational speed of the handle. The reverse movement occupies about one-fourth of the forward movement's duration. I also pushed myself to use only 3D printed components, eliminating the need for fasteners. This mechanism could prove useful in applications requiring pick-and-place movements, though it currently serves as a desktop curiosity.
