Marble Wheeled Superbike

A 3D printable motorbike that rolls on real marbles with smooth kinetic motion.
Print it in an hour and watch it glide like a vintage speed machine.

This retro race bike 3D print combines vintage motorsport styling with a fun functional mechanism, making it ideal as a fidget toy, desk toy, or collectible display model.

This compact 3D printed toy superbike is split into 7 easy parts (main body left and right, fairings left and right, fuel tank, headlight and connector pin) and is designed for fast printing — can be fully printed in around 1 hour depending on settings and printer speed. Perfect for quick makes, low filament usage, and rapid prototyping.

Assembly is simple with a snap-fit design, requiring no glue, no screws, and no AMS/multi-material system. 

The design uses two 15–16 mm marbles as wheels, creating a low-friction kinetic rolling system that delivers smooth motion and a unique driving experience. This makes it perfect as a kinetic toy, stress relief toy, or interactive desk gadget.

Optimised for 3D printing, this model requires minimal supports, is PLA-friendly, and is designed for easy printing on most FDM printers. A great addition for fans of MotoGP models, vintage bikes, TT, and functional 3D printed toys.
