Here comes another LEGO marble run machine masterpiece from Rimo Yaona.
The colorful GBC Ball Rolling Machine 12 is a fantastic LEGO build from this creative Japanese designer featuring three main rotating blocks holding two buckets each.
The GBC balls are falling two by two into these buckets and are doing some rotations. Whenever a bucket is meeting the one held by the liftarm nearby, the liftarm it is attached to is twisting 180 degrees, freeing up the transported balls into the next bucket.
Super reliable, impressive and fun to watch, this LEGO GBC module can be powered manually or via a motor. This LEGO Great Ball Contraption is also very fun to build (can easily be built with kids).
Let's go on a rotating ride, available now on Build-a-MOC as a ready-to-build set !!
