Customizable Marble Machine
thingiverse
Get the creative ball rolling and design your own custom marble machine! I've created a set of 3D printed parts that allow you to build the ultimate marble run, no matter how big or small you want it. With crossovers, loops, switches, and curves, you become the master roller coaster engineer. Inspired by the marble machine at Maker Bot's retail store, I just had to have my own - now you can too!
