Miniature lampshade

Today I went to the primary school that Nienke, Inge and Ellis used to go to.  I'm designing a farewell gift for one of the school teachers. Some of the children made some great black and white drawings and I've turned them into a 360 degrees lithophane for 3D printing. The idea is, to create a lampshade for an IKEA Lampan lamp. The lampshade in its actual size will take more than 30 hours to print, so I decided to scale things down and see if it would work. As you can see, it works quite nicely and the larger version will show even more detail.
