It has never been easier to build a complete Great Ball Contraption (GBC) loop yourself! This GBC is entirely built using only parts from the LEGO Bucket Wheel Excavator and can be referred to as alternate build of the 42055. When building, this GBC makes sure you master the GBC building techniques and tricks so that you eventually can build your own GBCs.
With a footprint of 89 cm (35 inch) by 48 cm (19 inch) and a height of 43 cm (17 inch), this GBC is quite a build! Using almost all the LEGO parts that come with the original LEGO set, you need to assemble over 3100 parts and go through 500+ pages of building instructions to great 10 individual GBC modules which all work together in harmony to make a full loop. In this way the ball flow will never end. The whole machine is powered by one LEGO motor which comes with the LEGO 42055 Bucket Wheel Excavator set.
