Need something to fidget with while you think up your next big idea? That's why Locknesters exists — they make handsomely sculptural 3D-printed puzzles that are endlessly fun to play with — like this little desktop friend. It's made of five printed pieces, hand-sanded, barrel tumbled, and top coated to a glossy, streaked shine. Futz with it while you brainstorm and you're that much closer to your next lightbulb moment.
