Wheel 36 is a very cool LEGO Great Ball Contraption module from the German builder mickthebricker.

This very compact GBC module is built with 36 “banana gears” (16 standard ones and 20 little ¼ circle gear rack ones), hence its name.

This ball machine is capable to process tons of LEGO balls at the same time thanks to its central wheel.

The mechanism is pretty simple but smart at the same time: the central wheel integrates smaller circular racks and ramps.
When the balls are entering the main wheel, they slide on the circular racks and fall down onto the central ramps, from which they find their way towards the outbox.

This big marble machine, that you can run manually or via a crank, can be easily reproduced with kids.

It includes some elements, giving a vintage style to the module.

Reproduce this LEGO bricks machine thanks to ready-to-build kits available on BuildaMOC. 
Motor + battery pack NOT included.
