Build a compact motorized marble run where precision-cut wooden parts come together to create continuous mechanical motion. This 3D wooden puzzle uses an electric catapult system to lift and launch steel marbles in a smooth, looping track, transforming engineering principles into a kinetic desk display. Once assembled, the motor keeps the marbles cycling automatically, making it both a hands-on build and a decorative moving sculpture. Designed for hobbyists and mechanical puzzle fans, it blends clean assembly, visible mechanics, and everyday visual motion in one compact model.

How to Use:

1. Sort all pre-cut wooden parts before starting assembly.
2. Follow the illustrated guide to assemble the structure (no glue required).
3. Install the motor and connect it to the battery compartment.
4. Insert the required batteries (not included).
5. Place the steel marbles into the track.
6. Switch on the motor and place the model on a flat surface to enjoy continuous motion.
7. Apply a small amount of wax if smoother movement is desired.
