GBC Ball Rolling Machine 11 is another massive outstanding LEGO Great Ball Contraption from the Japanese builder Rimo Yaona.
This huge build is making a clever use of the LEGO Crown parts: The top of these parts fits perfectly to the size of the LEGO GBC balls. Therefore, Rimo Yaona mounted them on several chariots, themselves being hooked to two giant wheels, and use them to transport balls. The GBC Balls, once caught by one of the chariots, are doing a sophisticated rotating ride switching from one chariot to another.
The mechanism from this GBC module is just awesome, making it an ultimate LEGO marble run machine, that you can add to your GBC collection thanks to building instructions available on Rebrickable and on Planet GBC.
A phenomenal must-have masterpiece!
