PlaySpirals is a construction toy, which can be used to build three-dimensional structures. PlaySpirals are a specially designed corkscrew-type of spirals. Two PlaySpirals can be put through each other at a straight 90-degrees angle. A third PlaySpiral can then be put through the first two. The full set has 28 spirals, the largest number that fitted with a single Shapeways model.
