The hand-driven gear train powers the lifts and switches. Turn the crank and enjoy the smooth flow of steel marbles along a track full of effects.
Complex gear sets, shafts, and splitters clearly demonstrate physics, technology, and engineering. Ideal for curious makers of all ages.
Accurately fitting parts made from safe, non-toxic materials ensure easy assembly, reliable operation, and an attractive finished look.
ROKR Climber is a hand-assembled marble run made from precisely laser-cut wooden parts. The elegant structure with a central “fortress” uses gears, shafts, and lifting mechanisms to guide marbles smoothly along carefully designed tracks. The kit develops technical thinking, imagination, and fine motor skills—and doubles as a striking decorative piece.
The model features a tower splitter, spiral slopes, a crane lift and wheel lift, a short slide, and cleverly placed switches that change the marbles’ path. Difficulty is rated 4/5; assembly takes about 6–7 hours. Once finished, simply turn the crank and enjoy a dynamic show that clearly illustrates STEM principles.
