The Conveyor GBC module is a nice-looking LEGO Great Ball Contraption from Brick Eric. The originality of this marble run machine lies in the chain of the conveyor, which is made of LEGO Technic L-shaped liftarms. The assembly of the L-shaped rigid liftarms creates a surprisingly flexible chain which his carrying quite fast your favorite basketball and soccer balls to the top of the build. GBC balls can then slide through the “snake slide” (a sliding ramp designed by the GBC builder Akiyuki) either directly back to the entry bin, or to the next GBC module if you change the direction of the slide. You can reproduce this brilliant machine, made with easy-to-find LEGO bricks, thanks to free building instructions from Brick Eric. Enjoy the ride!
