Product Name: Step order Lift 3D Adult Wooden Logic Puzzle, DIY Adult Craft Kit
In this DIY marble runway, multiple tracks and elements are packed into one compact space. Each model can be used independently or attached front or side to our other marble slides of the same or different designs (2 or 4 models can be connected in pairs using the special connectors included in the kit). The rocker mechanism at the end of the run can send marbles in one direction or the other or both. As you build this ingenious wooden marble slide, you'll learn about the interaction of the drive and driven gears and the function of the counterweight. Everything you need for this fun DIY project is in the box, including pre-cut planks, 10 marbles, and wax and sandpaper (for best gear functionality). Each Ugears model kit, 3D puzzle or brain teaser comes with a order set of detailed illustrations. The Marble Run step hoist comes in 355 pieces and is rated "Premium" with an estimated assembly time of 8 hours.
