We are used to printing plastic trinkets but we just learned that you can 3D print a surface in different thicknesses so that it can pass or block light to show a detailed photo when a light shines behind it. We just uploaded Merida's photo here and generated an STL file, sliced in Cura, 6 hours later we have this piece that can be slapped on a cheap nightlight from Walmart. She is now asking 50 pellets for copyright.
