BrickWorld Chicago 2019 GBC SAWTOOTH Lego Great Ball Contraption Module

Today I present my version of SAWTOOTH.  A Lego GBC Module designed by John Brost.  This module was created for use as the BrickWorld 2019 Chicago GBC Workshop Module.  It uses a Jigsaw style lift and is powered by a Lego Power Functions M Motor.


I've skinned my version to be mostly light and dark grey, I also added a rainbow colour to the lift mechanism.  I call this variation "Grainbow".


I built mine only using the parts list, a video clip, and a cover image.  No instructions were available at the time of the build, which made this quite challenging yet satisfying.


Please enjoy the video.

  1. I am wondering how I can source the parts list and build instruction for this GBC. I was unable to attend the Chicago show. Do you know if someone is going to put together a parts kits for it
