Futuristic, Sci-Fi Marble Run
Designed with six diversion mechanisms and five layered tracks, including transparent acceleration sections, this marble run is a miniature space adventure. Its dark gray and silver tones give it a futuristic look, making it both a mesmerizing tabletop display and a STEM-inspired gift.
4-Star 3D Puzzle Challenge
The model takes around 5.5 hours to build, a challenge that enhances skills in logic, patience, and spatial reasoning.
Durable Assembly With Tight-Fitting Parts
The puzzle uses a mortise-and-tenon joint structure, so each piece interlocks tightly without glue. It's eco-friendly and clean, and parts will hold firmly even after hours of play.
Manual or Automated Modes
Control the pace by turning the manual crank to power the marble lift or use the built-in motor for automatic operation. You can observe the clever mechanics with either option.
Expansion-Ready
The Marble Spaceport is compatible with the ROKR Night City Marble Run when connected through the special link pack. Together, the two models create an even more elaborate system, powered by a single motor.
STEAM-Rich Experience
More than a display, this model teaches physics and engineering principles in motion. It's a practical lesson on STEAM concepts like gravity, momentum, and mechanical energy transfer.
Each ROKR kit includes a printed instruction manual. If yours is lost or damaged, you can download the digital version below.
