This is The Labyrinth, my third major ball machine and the single largest K'nex structure I have built to date. This ball machine features 4 motorized lift towers spread across my room which split off into 19 different paths. To build this project, I spent over $150 to purchase literally over 9000 new k'nex pieces, allowing me to build this 25,000 piece superstructure. Despite its massive size, The Labyrinth only takes up 2.5 square feet of floor space. This machine was designed by Austin Granger and Paul Davis, and was built by Austin Granger, Paul Davis, Sam Ihlenfeldt and Simon Olson.
