Shrinking the World's Largest Nerf Gun - A Journey of Miniaturization

TLDRWe embarked on a mission to shrink the world's largest Nerf gun into a tiny, functional version. By utilizing compliant mechanisms and 3D printing, we achieved a one-part, spring-free design capable of firing darts. We share the design files and showcase the power and precision of our miniaturized creation. Join us on this journey of engineering ingenuity!

Key insights

🔍The challenge of miniaturizing the Nerf gun involved replacing mechanical springs with compliant mechanisms, which store and release energy through clever use of flexible materials.

⚙️The final design of the miniaturized Nerf gun utilized a zigzag structure, capable of storing energy efficiently using flexible bending mechanisms.

💥The miniaturized Nerf gun fired darts approximately three feet, achieving its design objective scaled down to ten times smaller than a standard Nerf gun.

🎯A accuracy contest was conducted, demonstrating the precision and power of the miniaturized Nerf gun.

📐The design files for the miniaturized Nerf gun are made available for free, allowing enthusiasts to print and experience miniaturized Nerf battles.
