LEGO GBC – Cup to Cup Module

Let’s have some small GBC Models!

Great Ball Contraptions can be found all around the world, created by dedicated LEGO fans.

It’s something you got to see in action

Main Idea

In order to get small GBC modules I propose that modules should be able to work standalone and linked to other modules. Linked means that balls are received form one module and will be passed on to another module. Standalone means that balls are only looping within the module. This way it’s possible to start by getting just one module.

Further I focused on creating modules that have a reasonable, smaller size.

About the Model

This GBC module is based on the Cup to Cup principle than can be found in the well-known GBC modules by Akiyuki (https://www.youtube.com/user/akiyuky).

The build is a combination of traditional and technic bricks, which is quite common for Great Ball Contraptions. The main challenge for me was basically to bring the size down to the base size I had in mind, which is 16 by 32 studs. In order to achieve this small size I developed a customized inbox dispenser with a fitting lift arm and feeding track. This model is composed of around 630 pieces.

The Module is powered by a LEGO M-Motor but also can be operated by the hand crank option easily. It’s actually interesting to operate the module by hand in standalone mode. So the motor and battery box don’t have to be included into the set. The Power Functions Tuning-Set (8293) would be an option to motorize this set.
