Made from 3D printed PLA, this clever mechanical puzzle was invented over 40 years ago by Vladimir Krasnoukhov. Originally called “Emelya’s Stove,” the name draws from Russian folklore—though the cultural reference doesn’t easily translate, hence its English name: the Non-Infinity Cube.
The puzzle consists of 8 hinged cubes that fold and pivot in unexpected ways. Your first task is to fold the chain into a perfect cube, but the challenge doesn’t stop there—try your hand at 23 additional shapes that test your spatial reasoning and creativity.
