Get lost in the motion of mechanical engineering with the Motorised Rainbow Ladder GBC, a mesmerizing Great Ball Contraption build constructed from over 1200 pieces.
Designed for builders who enjoy complex mechanisms, moving displays and kinetic engineering, this model uses a single motor to power an intricate network of gears, rods and conveyor movement.
The marble system features motorised ball feeding with a step-ladder style loading mechanism, moving the marbles upward before sending them through the track in a continuous mechanical rhythm.
Its 3-axis conveyor movement creates a hypnotic display of coordinated motion, making the finished build both technically impressive and visually satisfying.
Powered by PRO Series electronics, the Rainbow Ladder GBC is built for collectors who appreciate clever engineering, kinetic display models and repeatable mechanical play.
Build the mechanism. Load the marbles. Watch the motion.
