Lego GBC Spiral Lift Module

7 comments

This lego great ball contraption (GBC) module features a spiral mechanism made of  technic "banana" gears to lift the balls. 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. You can watch it running here:

Hope you like it :)
