A larger version of the Apple Puzzle( www.shapeways.com/model/286202/apple_puzzle.html). This is a simple "take apart/ put together" puzzle. There is only one way to fit the two halves together, but the "core" can go any way. Hope you enjoy!
Tips: If you think you put it together incorrectly, just pull the two halves apart - it should not break.
If you are not sure how to put it together, try leaving out the "core" and use a pencil instead.
