FAQ

How does a 3D wooden marble run kit work?

You will assemble a series of interlocking wooden gears, tracks, and lifts. Once built, turning a hand-crank or winding a mechanism sets steel marbles into continuous looping motion while cranked or wound.

Is wax required for the moving gears?

Some models may benefit from light waxing if the instructions recommend. It reduces friction and ensures your no-glue mechanism runs as smoothly as possible.

How much space do I need to build a marble run?

You do not need a garage or dedicated workshop. A standard dining table or a clean desk provides plenty of room to lay out the laser-cut birch sheets and enjoy your focused project.
