JBV Creative designed this interactive marble coaster that can be wall-mounted. To build the maze, he created 3D models in Solidworks, then rendered the components on a 3D printer. Once it’s loaded up with marbles, it continuously recirculates with the turn of its crank. You can buy the STL files to make your own on JBL’s website.
THE BEST Marble Machines
DeepMake sells these modular marble runs that stick to metal surfaces like a refrigerator. The pieces are made from laser-cut wood, and include ramps, loops, spinners, and stairsteps which you can configure any way you’d like. They come in 12-, 24-, 48-, and 96-piece sets, and are also working on a archimedes screw lift.
Builder Ben Tardif created this impressive motorized marble machine which carries hundreds of ball bearings up an elevator, then rolls them down a miniature ski jump, where they make their way back to the bottom to repeat the feat. You can check out the build process if you’re interested in seeing it come together.
