About this 3D model

Introducing the Marble-Bot-3000, the newest development in marble run technology. Use the special wind up key to spin the special panels on the Robot's chest and reroute marbles on their journey up and down the Robot's circuitry. How many marbles can the Marble-Bot-3000 keep in operation? This Marbleous Adventure is designed to be printed entirely without supports! Makes a great printing project and is lots of fun to play! Designed for 3/8" marble bearings. Requires a 120mm cubic footprint. Follow me on Instagram @coolthingsbyjacob for more 3D printing projects!
