This is a design in a series of Optical Illusions I've created, many of which are inspired by the late Swedish artist Oscar Reutersvärd, who began painting 3D figure illusions in the early 1930s, with the Impossible Triangle (Penrose Triangle) in 1934 one of his most famous work.

The illusions are made so they're easily 3D printed without supports. They're generally only an optical illusion from a certain angle, I'll let you have fun and discover that angle yourself.

Print the model in the direction I have set it.

Hint: Close one eye or use a camera for best effect.
