The epitome of 3D impossible - M.C. Escher would be extremely impressed. A 3D object made with negative-space and 3D Printed in a physical architectural form absolutely impossible to make using historic subtractive, milling, molding, etc, manufacturing techniques. 3D enthusiasts be sure to download the Free STL file of the product and be amazed. We use this model in our lab as a demonstration of the laws of gravity and physics still at play in the engineering of 3D products.
