GBC 47 Mill Madness is the latest Great Ball Contraption module from PV-Productions, and what better choice for a Dutch GBC builder than to build a windmill, emblematic icon from The Netherlands ? This beautiful LEGO GBC module can be entirely reproduced thanks to the parts from the official LEGO set 42114 (“6×6 Volvo Articulated Hauler”). The huge marble run machine is functioning in full loop and figuring a giant windmill, made with the numerous yellow panel parts present within the LEGO set, a big fair wheel and three Cardan Gear Lifts, interconnected thanks to numerous LEGO ramps. The complete module is powered by two motors and the Powered Up system, that you can control remotely thanks to a smartphone app (included in the Volvo LEGO set). If you want to offer to your GBC balls some funny slides onto the wings of this giant windmill, then time to break (or buy) the LEGO set 42114 to reproduce this awesome and massive creation!
