Customizable Engraved Image Shade

Inspired by Van Alles Wat's [interactive lampshade design project](http://www.thingiverse.com/thing:288447), this customizable design allows you to upload an image to engrave onto the surface of a cylinder. By default, the cylinder is shaped like an Ikea Lampan shade, but you can adjust its size and proportions, as well as the depth of the engraving and a few other settings.

Works best with [depth maps](https://www.google.com/search?q=3d+depth+map&tbm=isch) or designs drawn in black and white
