This puzzle offers a simple, elegant challenge. The solution isn't instantly-obvious, but most people get it after a few seconds of thought. Its wafer-thin walls are a spectacular demonstration of the capabilities of the "strong & flexible" SLS material. It would be interesting to have it modeled in a more rigid material, as the SLS plastic is sufficiently flexible to permit the ring to be awkwardly forced together. (Not easily, though.)
