Honycomb Metal Puzzle

Honeycomb is an attractive metal packing problem. The object is to fit the seven screws flush into the big nut. The pieces have been designed in a misleading way, such that many packings fit partially, but then the last few screws don't fit. This makes it a confusing puzzle, even more difficult because your are unable to distinguish the pieces by their color.

Designed by Oskar van Deventer, who has created hundreds of mechanical puzzles, making him one of the world's most prolific designers.
