Marble Maze: Different Sizes & Challenges (6 mm)

Challenge yourself with three different sizes of mazes: 🟢 Small (8 cm - 10 rows/cols) 🟡 Medium (12 cm - 15 rows/cols) 🔴 Large (16 cm - 20 rows/cols) Perfect for timed challenges, these mazes offer hours of fun and excitement. Reverse the maze and start from the finish line for an entirely new experience!   I recommend using 6mm stainless steel balls or, as an alternative, making a ball out of aluminium foil or 3D printing one.
