Description

The Hyperboloid Burr is a six-piece burr puzzle made from identical hyperboloid pieces.

It was designed by Oskar van Deventer with the help of Naoaki Takashima. A wooden version was made as a limited (sold-out) edition for Naoaki Takashima by the Kanagawa Toy Company in Odawara. While working on the wooden pieces, the manager of Kanagawa Toy found an unexpected 7-piece solution. A 3D printed version is also available.

With Oskar's permission we have recreated the puzzle in Brass. We learned a few things along the way :

Brass is heavier than wood
Brass has lower friction than wood
Brass does not flex nearly so much as wood.

All this means our puzzles pieces have been machined to very accurate tolerances. The six piece version of the puzzle assembles and displays well, but if picked up by a single piece falls apart under it's own weight.

The seven piece assembly is completed with a satisfying "click" and holds together well - it's a fidgit toy in it's own right.

It turned out the tolerances for this puzzle were absolutely critical. A mere 0.03mm tighter or looser and the seven piece version of the puzzle either does not assemble or falls apart!

The pictures container no spoilers, neither the six piece or seven piece assembly is shown and the puzzle ships disassembled.
