One of our new models on the GBC 51 Gravel Works for the big LEGO set 42131 is the wave machine.
With 7 sections it is one of the biggest modules we have yet created and it is so much fun to watch in action.
A big upsell for this one is the height gain where the GBC Balls will roll uphill 7 studs higher when they reach the end.
Can’t wait to show you more!
