🚀 Scout-1 Modular Space Rover | Ultimate Planetary Explorer
One Chassis. Four Missions. 100% Support-Free.
Created specifically for the Makeronline Space Exploration Design Contest, the Scout-1 is a high-performance modular toy designed to spark the imagination of the next generation of astronauts. Engineered with a futuristic "Galactic Expedition" aesthetic, this rover features a universal 6-wheel heavy-duty chassis and four specialized mission modules that can be swapped out instantly for different exploration scenarios.
The Scout-1 isn't just a toy—it's a mechanical experience. It features an integrated Kinetic Fidget Wheel System, allowing the wheels to be printed in place with smooth internal bearings for a satisfying tactile feel as it rolls across the lunar surface.
