MOTORISED GBC HARP TRACK MARBLE RUN | 1510PCS
Presenting the first marble run with a customisable track — where creativity meets engineering.
The Harp Strings Marble Run features adjustable tension cords that let you reshape the marble descent path to your liking, creating a dynamic, ever-changing downhill experience.
Equipped with a powerful PRO Series electric motor, this model powers both the ball feeding system and the climbing mechanism, enabling a continuous loop of movement from start to finish. After completing the course, marbles are collected in a return box and sent back up automatically.
Designed for hands-on interaction and endless motion, this build is as satisfying to watch as it is to assemble.
