Fractal Gigamaze is a huge ball maze with a fractal maze pattern based on the dragon's curve. The first challenge in building this maze was the choice opf material. Plain PLA warps too much, resulting in an unusable warped maze. Even brims could not keep the maze onto its built place, it just pulled the magnet mat up. 3D-printed wood resulted in a beautiful flat maze, but with too much tiny pieces of fibre sticking out, blocking the rolling ball. The solution was to print the base in wood, and only the maze layer in PLA. The second challenge was the tinyness of the rolling ball. A 1-mm ball bearing fits well in the 1.5-mm alleys between the 1.5-mm walls, but it is hard to see and follow. The solution was the have 45-degrees tapered walls and a 3-mm ball bearing that rolls between the walls, partly hanging over them.
