Two-Dimensional Modular Maze

This is a dynamic maze composed of nine interlocking pieces, perfectly suited for children. The maze's shape and pathways are endlessly variable, offering diverse gameplay and boundless fun.

• Red Modules: Cross-shaped design; allows passage from any entrance to any other.
• Black Modules: T-shaped design; one exit is blocked, while the remaining three are interconnected.

Based on these rules, puzzles with varying solutions can be designed!

P.S.

• Plate 3: 3D-printed balls lack the smoothness of traditionally injection-molded toys; consider substituting 5-7mm balls.
• Plate 4: A transparent top cover is recommended. Adjust parameters according to this tutorial and print using transparent PETG. If transparent filament is unavailable, the top plate can be omitted without affecting gameplay. Alternatively, a transparent film (e.g., a file folder) can be cut to the appropriate shape as a substitute.
