Cake Cast Metal Puzzle

This is no ordinary cake - you only acquire a 'slice' with top logic skills. One quarter has already been cut away, revealing three identical layers which must be removed to complete the puzzle. This is an attractive, tactile object of simple but ingenious design and a deceptively challenging puzzle.
