Descrição
Get the ball rolling and design your own custom marble machine. I have created a set of 3d printed parts that allow you to build the marble machine of your dreams as big or as small as you want. With crossovers, loops, switches, and curves you become a roller coaster engineer. Inspired by the marble machine in the Maker Bot Retail Store. I had to have my own now you can too. More info at:
