3D printed lithophane of John Davenport

This lithophane was created by Steve Nicholls from a digital photograph of John Davenport. To view the image properly it must be held up to a light. Steve is a UK puzzle expert and 3D printing enthusiast. The lithophane was created using an affordable 3D printer. The photographic image was converted to a grey scale and then turned into a 3 dimensional height map that is 3mm tall. The map has been printed in 30 layers on a THREEDY 3D printer using translucent plastic.
