Bavo Bakers from the Netherlands build our GBC 47 Mill Madness and got it working flawlessly! It takes quite some engineering to get this machine to work perfectly. I can imagine the satisfaction of finishing this build and getting it to run this smoothly is great! This machine is completely made form parts of the LEGO 42114 6×6 Volvo Articulated Hauler set. He even captured this video of his Great Ball Contraption in action. Thank you for sharing with us!
