Ledge Marble Run Piece

thingiverse

I built a marble run using OpenSCAD as a system of ledges that the marble must navigate. The design allows the marble to drop vertically and then bounce off the ledges, creating a high-speed movement that makes it almost impossible to see. I created two separate modules - one for the ledges themselves and another for the thumbtack holes that provide attachment points. My project is specifically designed to attach securely to a wall, but can also be adapted to any other surface with compatible thumbtacks.
