LEGO GBC Extending Forks Module

28 comments
This LEGO Great Ball Contraption (GBC) module features a mechanism that lifts the balls using two pairs of 40 tooth gears attached to technic lift arms. I built this module because I wanted it to be easier for people to get into building GBC modules, as it can be quite hard to build your first one by yourself. While it is quite a complicated module, it is still a really reliable module, and it can hold the GBC standard of 30 balls at one time. I think it would be a very enjoyable building process to rebuild it, as it uses a fun combination of system and technic bricks, as well as being satisfying to watch when it is done. Hope you like it!
