266pc Ugears Marble Run Spiral Hoist Mechanical Wooden 3D Puzzle/Model 14+

Assemble me. Let the marbles go! 
The Marble Run Spiral Hoist is the fourth model in the Ugears collection of fascinating DIY wooden mechanical marble runs. The hoist has two types of rails to speed the ascent: the main spiral rails and vertical rails. Turn the crank to lift the coloured glass marbles upwards (one marble rises per nine revolutions of the winding crank) to the three-marble storage up top. From there the marbles begin their downhill runs through exciting elements: a high-speed slide, a vertical snake and a mountain river.
