Explorer the world of GBCs by building our GBC 18 Port Factory C Model of the 42064 Ocean Explorer Set. With this GBC loop model featuring 4 cool modules it has never been easier to build a complete Great Ball Contraption (GBC) loop yourself! All GBC modules work together in harmony in a complete loop so the ball flow will never end. This GBC is entirely built using only parts from the LEGO Ocean Explorer and can be referred to as model C of the 42064. This GBC makes sure you master the GBC building techniques and tricks so that you eventually also can build your own GBCs.
Mechanisms, Gearing, Physics and so much more
The Mechanical Lift Arm Module takes one ball at a time and transports them in a perfect vertical line to a higher level. A really efficient, but complex, interesting module which is a real eye catcher of the build.
This module brings the GBC Balls to the Tilting Bucket Module. The bucket, created from the nose of the original boat, takes 3-4 balls (depending on how it fills) and then drops them on the base plate. Due to perfect contra balancing and a special building technique you can control the dropping of the GBC Balls (more info in the building instructions).
This guides the balls to the Seesaw Module which does move like is says. Take one or two ball(s) on the low side, brings them to the other side of the seesaw, brings them up and releases the balls at the top by the use of a small door triggered by the LEGO rope.
There the balls are picked up by the Wing Push Module to take one ball at a time and take them to the first module again. By using the correct gearing the ball flow will never stop and the timing is perfect. A handy hold will keep your battery box in place.
Fun Fact
Our GBC 18 Port Factory started with the Vertical Line Lift Module. This module converts a rotating motion into a perfectly straight line motion. By tweaking the beams and levers we were able to get the tilt motion required for the GBC Balls to fall out. It was not easy but in the end everything worked out great!

A large GBC, rather complex in its form and its operation (I would have put it in “medium” by the way), and take advantage of many particular parts (not Technic). Lots of movements allow the balls to move up and down in several places.
It’s a pleasure to see those movements follow one another with good timing.
For these reasons, it is a model worth building.
I stayed with the manual movement because sometimes the balls are blocked or come out of the rails, despite the care taken in the balancing, so I can adjust the shot by moving slowly.

Something about this GBC i am just in love with. It may be the out-of-the-box modules, or that it kinda reminds me of an actual port for some reason, But i absouletly had a blast creating this one and would definately recommened to new-comers.
Sidenote: buy the motor and battery box, Its soooo much better with them!
Once again, Ahuge, massive and ginormous thanks to the PV- Productions community. You people are on the ball with what others want. Keep it up!!!!
Thanking you all,
Jason
