The hexasphericon exhibits a unique rolling motion due to its continuous, curved surface. As if that isn't enough, this Quantum Wireframe Sphericon is reduced to thin 1mm 3D printed wires, with the skeleton of another sphericon trapped within. Cast metal printing makes the part stronger than expected given it's delicate appearance, and the weight of the metal lends itself to a better rolling motion (though it still requires a precise push or an ever so slightly slanted surface). This beautiful object really must be held to fully appreciate!

Pictured model was printed in Cast Bronze (Natural) by Shapeways Print-on-Demand. It is 42mm wide.
