Building a LEGO ball machine has never been easier!
Discover Triangle Conveyor, the first LEGO Great Ball Contraption module of the GBC4ALL series: easy to build, easy to configure, crankable or motorized, and made with only most common bricks.
Building a super cool GBC module has never been simpler.
Triangle Conveyor can be chained with other GBC4ALL series modules, or with multiple modules of the same type (with up to three modules powered by the same motor), to build an amazing ball circuit.
With its ascending conveyor belt, the Triangle Conveyor is very nice to reproduce by children.
The visible gearing of this compact marble machine allows your child to discover some basic mechanical principles while having fun.
