One year ago we released our biggest, most ambitious and greatest GBC 15 Mining Plant (42055 LEGO Set C Model) yet! The response was overwhelming and many many builders had a blast building it! In a few weeks we will release our NEW GBC 21 which takes everything even one step further! More complex, astonishing and mesmerizing mechanisms that work beautifully together in moving lots and lots of GBC balls around in an infinite loop. This is gonna be awesome! Stay tuned!
