Key M<aze

This CAD model was designed by Oskar van Deventer, copyright (c), 6 September 1987, 12 November 2006.

Key Maze is one of my early mechanical mazes. It was sold in metal by Bits&Pieces. Several versions have been brought to the market in plastic and wood, most recently by Cubic Dissection and Project Genius. I designed the original in 1987. I designed the variations in 2006. They have some fun mix-and-match properties, so please try them all, and swap keys.
