Marble Motorbike

A compact, multi-part 3D printable toy motorbike designed to roll smoothly on real marbles for a unique and eye-catching finish. This model is printed in 5 separate parts: left frame, right frame, connecting pin, sliding fuel tank, and press-fit headlamp.

Assembly is simple and tool-free—the pin joins the frame halves, the fuel tank slides over the top to lock everything securely in place, and the headlamp press-fits into the front. No glue, screws, or supports required, and no AMS or multi-material setup needed.

Designed to use two 15–16 mm marbles as wheels, the bike combines mechanical simplicity with a fun, kinetic design.

Perfect for makers looking for a quick print, easy assembly, and a satisfying result. Great as a fidget toy, desk toy, display model, gift, or beginner-friendly build.
