A fun little project that turned out way better than expected.

These three threaded containers nest perfectly inside one another when empty similar to a mechanical matryoshka set.

The twist texture gives the containers a clean grip, the threads print smooth, and the whole set feels great to handle. My coworker thought this would make an awesome toy for his grandson… and honestly, I kind of agree. They’re equal parts storage, fidget, and desk toy.

Features

• 3 different sizes all nest into the largest container
• Twist pattern for grip + aesthetics
• Smooth internal/external threads that print cleanly without supports
• Space-saving design for drawers, desktops, or toolboxes
• Surprisingly fun for kids (and adults) to twist and slide apart

Use them for small parts, trinkets, or just something tactile to fidget with.
