Impossible Puzzle Box Plan

Not all boxes are for storage -- some are clever puzzles that confound your every attempt to open them. This ingenious puzzle box is particularly difficult to solve for the simple reason that it doesn't open like a box. The box comes apart with a unique sliding motion that you have to see to believe. As it does so, it reveals several small compartments where you might store tiny treasures. Author/craftsman Nick Engler provides step-by-step instructions and detailed drawings plus three full-size patterns for boxes in the shapes of a heart, hexagon, or cog. Includes plans in both English and metric measurements. Files:    1 PDF
