Solve the picture to open the box.
(These are digital plans. Please see my other listings for the physical kit)

We have all toiled over these slide picture puzzles as kids, only to find ourselves
stuck with one little piece impossible to get into the correct position without undoing
all of our hard work. As an adult I feel I have finally put this conundrum to rest and
have discovered the secret method. I then set about designing a secret box
that can only be opened by solving one of these engaging little slide picture puzzles.
Here is the result. The secret method is etched on the wall panels. The image to
unscramble is Leonardo Davinci's famous Vitruvian Man.

You will receive files suited to 3.1 - 3.3mm thick wood, but the file can be scaled to match your thickness. Please read the pdf "how to cut" page to ensure you get correct snug fits that make the mechanism function properly.

I have made these from 3.2mm birch ply and 3mm MDF
