Craighill Venn Puzzle - Stainless Steel

A Perfect Sphere

Mentally stimulating and beautiful to hold and behold, the Craighill Venn Puzzle is a mechanical wonder that would elevate any tabletop and provide endless hours of cerebral and visceral enjoyment.

Mechanical puzzles have fascinated designers and engineers for hundreds of years. And in the Venn Puzzle, the team at Craighill took on their most complex project to date. It took 2 years to fine-tune the geometry, refining the finishing process.

The result is something familiar yet different. A perfect sphere of solid stainless steel that revels in the contrast of the rougher, angular interior faces, against the smooth, curved exterior surface.

The Venn Puzzle is comprised of three identical pieces of stainless steel. Each piece makes up one-third of the sphere by volume. These pieces are cast from molten stainless steel in a ‘die’ or mold at temperatures over 2500°F.

The process of assembling the Venn Puzzle can offer a meditative break during your day or occupy your hands while in conversation or deep thought. Use it to challenge your friends, to surprise a puzzle lover, or simply to ponder the density of solid stainless steel.
