ROKR 3D Wooden Puzzles Marble Run Model Building Kit


This marble run model can be put on a bookshelf and believe that your friends will always ask you what it is and want a demonstration. Build it with 294 pieces and 10 marbles. The end result is pretty cool, it has a crank that uses large gears to move marbles up to the top of the machine where they roll down into different channels.

This one was more advanced, different from other wood puzzles, black-grey appearance, metal nameplate, and acrylic pieces make the finished product more visually interesting and allow the balls to be seen in action more.
