New GBC modules from Rimo Yaona are always coming along with fresh and innovative ideas. And GBC Ball Rolling Machine 15 is no exception to the rule.

The main innovation from this very cool LEGO Great Ball Contraption module resides in its central clamps, which are opening and closing in alternance and grabbing the GBC Balls two by two to bring them toward the exit ramp.

The clamps block is tightly attached to a rotating ramp in the back of the module and its motion is guided by a global sliding frame giving to the mechanism the required directives.
A big wheel and a smart loading mechanism complete the build, allowing the balls to be grabbed by pair.

You will certainly spend long minutes watching the mesmerizing movements from the clamp of this formidable LEGO marble run machine, a Great Ball Contraption that you can easily reproduce thanks to BuildaMOC ready-to-build LEGO set.

Have fun with this spectacular GBC module!
