The puzzle pictured is made of 1/8" Oak for the inner box, 1/8" Cherry for the outer box and 1/8" Walnut for the sliders. The entire box was finished with a coat of clear lacquer.


You may have seen those puzzles based on a bicycle chain combination lock, where a series of rings are turned to a certain number, and the inner barrel can be pulled out. Those puzzles are bigger, usually made of wood, and the rings have letters. When the letters are turned to spell out a word, the inner cylinder can be withdrawn.
This is my version of those “Cryptex” puzzles, but mine is a box, not a tube. Each side has six sliders, and each slider has three positions, making 2187 combinations of positions per side. Every slider has to be moved to a certain position before the inner box can be withdrawn. Total number of combinations is 2187 by 2187  four times. The inner box is hollow, so you can keep stuff in it.
Without the solution (and you can make your own), you may not live long enough to get the inner box out!
The puzzle measures 5” by 3” by 3”, and is made from 1/8” wood, and there are 142 pieces to this puzzle.

This puzzle kit has alignment pegs built into the parts to make assembly easier and virtually every part in the kit is labeled.
