Fidgeting isn’t just a modern-day habit—it’s a centuries-old craft. In this deep dive into the hands-on history of fidget toys, we explore how these tactile tools evolved from ancient curiosities into precision-engineered marvels. From Baoding balls to ball bearings, we uncover the ingenious designs that keep fingers busy and minds focused. At MetMo, we celebrate the fusion of engineering and play—because sometimes, the best ideas come when your hands are in motion.

But helical gears are great – to look at and to use. And you’ll find them in a lot of places. So let’s get our butts into gear and explore these smooth criminals of the engineering world.

In MetMo's latest update, the team shares exciting progress on the Helico project, focusing on packaging enhancements and pre-production refinements. They've partnered with a local foam specialist to create custom inserts, ensuring that each Helico arrives safely—even if it's drop-kicked into your garden. Additionally, final pre-production units are in hand, allowing for meticulous testing and quality control.

Meet Helico—the world’s first helical gear fidget toy engineered for minds that never sit still. Precision-machined with the same gear geometry found in jet engines and performance vehicles, Helico delivers a uniquely satisfying spin, click, and feel. Designed by MetMo for engineers, makers, and thinkers, it’s more than a desk toy—it’s a kinetic celebration of mechanical ingenuity.
