This electric mechanical marble run is a precision-designed 3D wooden model that combines engineering structure with dynamic motion. Powered by a built-in motor, the system runs automatically using two AA batteries, setting the entire mechanism in continuous movement.
The model features a multi-level marble circulation system with lifting wheels, transfer platforms, and dual spiral tracks. Marbles are carried upward by the motor-driven lift, distributed through layered chambers, and guided back down along smooth, curved paths, creating an uninterrupted loop that is both functional and visually engaging.
Each component is laser-cut from natural wood and engineered for accurate assembly. The layered construction highlights exposed gears, guided channels, and structural joints, allowing builders to clearly see how motion is transferred throughout the system.
