This is a really fun puzzle to spring on people. I’ve noticed that it is easy to take apart, but hard to put together. So I’ve been showing people the completed shape, then taking it apart without them watching. Then I stand back and watch the hilarity ensue as they wrack their brains for hours trying to put it together. If you would like to build one, here are detailed plans that Timothy Sluder drew up. Enjoy!
