UGEARS Marble Run

This 3D model for self - assembling is made of plywood. Model size: 10.6*12*10.6 in Number of components: 400 Estimated time for assembly: 7 hours The Marble Run Chain Hoist is both a beautiful kinetic sculpture and an intricate toy that teaches as it entertains. This DIY wooden marble run features a chain hoist powered by a hand crank, and a series of tracks, each with its own unique and fun obstacle or element. One marble plunges down a chute with a loop-the-loop at the bottom; the next tumbles down the various stages of the cascades, while three others are collected in the accumulator then released down one of three short tracks. All marbles pass through the common tray or collector before returning to the chain hoist to be lifted on their next journey.
