Mesmerizing mechanical puzzle with interlocking iris-style petals
Twist and unlock the segments to reveal the hidden chamber inside
Print, snap together, and start puzzling—no glue or tools needed
A playful twist on the classic iris box design, now in sphere form

The Iris Ball is a clever 3D printed toy that brings the satisfying mechanics of an iris box into a spherical puzzle. Inspired by popular designs across Thingiverse and the maker community, this version reimagines the classic sliding-petal mechanism as a twistable ball that conceals a surprise chamber at its core.

Twist the segmented outer shell to align the petals, then watch them slide open to reveal what's hidden inside. It's part fidget toy, part brain teaser, and entirely addictive once you get it in your hands. The interlocking design snaps together after printing, so you can go from print bed to puzzle in minutes.

Whether you're prototyping new toy ideas or just love mechanical puzzles, the Iris Ball delivers that perfect blend of engineering and play. Mashup-friendly, too—pair it with two-color prints or custom finishes to make it your own.
