Marble Run Fidget

The Marble Run Fidget combines a rolling steel marble with a ring of rotating gears. Turning the six gears reshapes the interconnected track, creating new paths for the 8 mm steel marble to explore. With many ways to arrange the gears, you can generate a wide variety of track layouts, making this model both a fidget toy and a puzzle.
