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 (check the BOM) or, as an alternative, making a ball out of aluminium foil or 3D printing one.
