There is something strangely satisfying about marble runs, no matter how old you are. You drop a marble at the top and watch it roll, turn, and finally reach the end. For this Flash Contest, design a 3D printable marble run that makes that little journey fun to watch. It can be a simple track, a set of ramps, a spiral, a funnel, or a small modular system. You only have 17 days, so there is no need to overcomplicate it. But if you want to add a switch, a moving part, a themed element, or make good use of tree supports as part of the look, go for it. As long as the marble gets from start to finish and people want to try it again, you’re on the right track.
