Intricate Mechanical Machine: Gears in Motion

Create a mechanical machine with exactly three gears, each connected by a chain or system of rods, mimicking the functionality of a bicycle's gear system. The first gear, located at the front, should be small and fast, made of shiny metal with sharp teeth, representing the fastest gear, rotating quickly. The second gear, medium-sized, is placed in the middle, with sturdy teeth and a moderate speed, acting as a transition between the first and third gears. The third gear, located at the back, is the largest, with thick, durable teeth and rotates slowly, symbolizing the slowest gear in the system. Ensure the gears are connected by a visible chain, similar to a bicycle, where the small gear drives the medium gear, and the medium gear drives the large gear. The rest of the machine can be filled with industrial elements like tubes, rods, buttons, and panels, creating a functional and mechanical look. The primary focus should be on the three gears and their interconnected motion.
