I'm short on ideas as well, but here's a couple of materials that might help you avoid having to drill a lot of holes. You could build zig zag path for a marble. You might do something where you make a basic ramp by screwing straps into a board and bending them into legs. You can use additional straps and screws to create the path. You can use a tube to drop the marble in, and if it's a steel bearing marble, you can use a magnet at the end to stop it in place.
