The Kid Should See This

Machining a cube in a cube in a cube from a single metal block

Watch more with these video collections:

This three-layered cube – a cube in a cube in a cube – was made from a single block of metal. It was machined with precision on a metal lathe and a drill by YouTuber Инженер BrunS, an experienced hobbyist. The cubes cannot be separated, yet they shake about within each other as if made separately.

In the time lapse video above, куб в кубе, you can see how it’s made, from solid metal chunk to three puzzling pieces. The key final step: Gluing the drilled sides to hold everything together while drilling the sixth cube face.
