NEW – The Building Instructions for the GBC 56 Mine Quarry are finally available! Created completely from the LEGO 42055 Bucket Wheel Excavator set.

This GBC is one of the most epic ones yet with a lot going on in every corner. GBC Balls can take multiple paths and you can control the direction however you like! Learn about clever mechanisms and experience how systems work together to get the GBC Balls go round and round.

Bricknerd (a LEGO news outlet) challenged us (together with Noad de Lange, Petter Breedveld and Ben Jonkman) to make a GBC from the small LEGO 42167 Mack LR Electric Garbage Truck set. Due to the very limited parts selection it was indeed a good challenge where everyone contributed ideas from their own expertise. We had a blast designing it together and in the end we accomplished the goal of making a nice functional GBC which is also very satisfying to look at.

We may now proudly reveal: GBC 58 Dump ‘n’ Drop – 42167 Alternate Build Building Instructions

Noah de Lange from Bricknerd wrote a really nice article about the design process of this GBC.

The news is out. The GBC 56 Mine Quarry will open its doors this week!
The machine is made from parts of the beloved LEGO 42055 Bucket Wheel Excavator set and uses almost all parts!

Mark your calendar! Next week on November 28th we will release the free building instructions for the new GBC 58 Dump ‘n’ Drop, an LEGO 42167 Mack LR Electric Garbage Truck set alternate build. Learn more about this machine, the working and mechanics on the product page. A perfect build to get started with Great Ball Contraptions.

And that means, time for giving!

This year we are working on making free GBC building instructions for the LEGO 42167 Mack LR Electric Garbage Truck set. This GBC uses neat mechanisms to get you inspired to start building your own GBCs these Holidays. Perhaps even from the same set. What can you come up with?
