The file 'Hogwarts Lithopane 3D Printer Model' is (stl) file type, size is 16.9MB.
The first lithopane I've made from scratch, using inkscape to convert photos to .svg, then importing the .svg files in blender.
Much of the detail was lost in the slicing process, therefore a larger print would have much better results.
