A good old GBC which is still running strong, even during LEGO World 2023 this year. Of course we are talking about our GBC 13 Extended Belt Lift made from the LEGO 42042 Crawler Crane set. Jorian Doornenbal from the Netherlands made this nice video of it even featuring our GBC Glow in the Dark Balls.

We use it very often in display as it makes the GBC layouts very flexible. Have you also build this classic GBC module yourself?

Bennie te Veluwe from the Netherlands did a great job building, programming and filming our GBC 45 Stunt Circus from the LEGO 42100 Liebherr R 9800 set.
Always so much going on in this GBC, it is hard to keep track on were the GBC Balls are going.
Thanks for sharing with us Bennie. We appreciate it! Share your creation as well via our upload page.

Szilard Gyalay from the USA build our GBC 51 Gravel Works from the LEGO 42131 CAT D11 Bulldozer set.
We couldn’t be more fond of his review. This is what Szilard had to say:

GBC 51 Gravel Works - 42131 Building Instructions

Szilard Gyalay - October 2, 2023

I believe it is one of the best builds yet, with very stable lift mechanism simple conveyer belt and great use of gravitational forces for the „tilt-drop“ . The wave mechanism needs some tune-up but works well after. Dismantle and build about 8 -10 hours , Worked in the evening. I actually dismantled my CAT11 to build this.

He even included a video which can be seen below.

Our GBC 10 Funfair is already 7 years old. The cool thing about LEGO is that you can rebuild anything, anytime you want. So did Jorian from the Netherlands and this is what he wrote us. See also the fan build he send us!

6 years ago I bought and build the GBC 10 Funfair. After that I have sold the LEGO set but recently I got the set again and the first thing I did was to rebuild the GBC 10 FunFair. PV-Productions truly got the most out of this LEGO set and after building you are left with not much parts. Very well done! I also create my own GBC now and I like it a lot! Thanks.

Thanks for sharing this with us Jorian and hearing the nice words!

Our friends at Toypro wrote a nice article about our latest GBC 51 Gravel Works. A model made from all the parts of LEGO 42131 CAT D11 Bulldozer set.
Check out what they have to say about it and, while you are there, why not get the LEGO set there as well.

So many things are happening, GBC balls are rolling everywhere in the GBC 51 Gravel Works. With 6 modules and lots of paths for the balls to roll over, this GBC has a bit of everything. PV-Productions, the well-known makers of GBC machines (Great Ball Contraptions), have made another great machine. This time from the set 42131 Cat D11 Bulldozer (App-Controlled)…..
