|Make a sort of 3D object|
|From a photo, convert to svg, 2 contrast settings|
|High contrast svg|
|Combine 2 svg versions in TinkerCAD|
You now have the 3d item at the top, which you can 3D print. It isn't very realistic, but it has a style of its own. I used Paint .Net to process the photos, and Inkscape to conver to .svg.TinkerCAD can import the .svg files.
