    Fantastic structures. I can even see fine patterns on the molds as well. Also; this gives me an idea to test resolution limits using molds – since soft lithography is known to replicate nanometer scale steps; we could easily study what step size in a mold would be visible under a foldscope.

    Here is an extreme of replica modling:
