3D Printing the Impossible: A Penrose Triangle

An impossible object is a two-dimensional figure that, at first glance, looks like a real 3D object. However, further inspection will lead to the conclusion that the object can’t actually exist in 3D. One famous example of this is the Penrose triangle. The concept was used in M.C. Escher’s famous Waterfall, and you might also recognize it as Digilent’s logo.
