Puzzle shelves

This is a half-height bookshelf made from 5 pieces of 3/4" plywood cut from a 4x4' blank according to the plan below. This prototype was made from Finnish plywood, stained with Minwax "Island Water," and treated with boiled linseed oil.

he parts have been designed to minimize wastage in the parts blank while maximizing available shelf space. The puzzle shelves unit can stand up against a wall to provide a "fourth shelf" below the other three, or it can be turned over and stand on its own.
