Modular Marble Maze
thingiverse
A peg board with 6mm holes at a 27mm separation can be used as a base for creating a marble maze. Simply place various OpenSCAD-designed pieces on top of the grid, ensuring they fit into the holes. Arrange flat or hole models on each base and insert wall or spacer models between them to customize your maze layout. Note that this is an untested concept design.
