Description
A new, improved F1 race car that rolls on real marbles with smooth kinetic motion.
Now with legohead compatibility!
This race car 3D print combines 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 car is split into 6 easy parts (main body shell, chassis and wheel housings) and is designed for fast printing — can be fully printed in under 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. Just ensure the correct wheel housings are placed in the correct positions for proper alignment and smooth rolling performance.
The design uses four 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, marble wheel car, 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 Formula 1 models, vintage race cars, Grand Prix history, and functional 3D printed toys.
