Holey Octahedron

Holey Octahedron custom Rubiks cube type twisty puzzle like Gentoshas Void Cube by Okamoto

I originally designed the Holey Octahedron for casting and it was built from FDM masters by David Calzone. In December 2009, I adapted the design to be suitable for printing in SLS. It features a hollow core mechanism, which is easy to produce but causes the holes to be blocked by the core during turns, so it is not a 100% hollow puzzle.
The puzzle rotates smoothly but assembly is a pain as it is somewhat difficult to insert the screws.

This puzzle can be bought as a DIY kit from my puzzle shop. A DIY kit contains just the 3D printed pieces needed to build the puzzle, you will need to supply your own stickers and screws, springs and washers (usually M3 size). I no longer sell assembled puzzles directly.
