While not 3D-printed, similar things have been done long before by Nikolai Aldunin. A TIME gallery features some pictures, among them perhaps most relevant at the moment a set of seven camels (plus three palm trees) in the eye of a needle and most impressive for me personally a flea fitted with horse shoes, saddle and stirrups. While TIME reported on him in 2008, most of the work is much older. I remember going to an exhibition in late 1980s.
The TopCoder reference is a really odd one. Code written in programming contests is generally not written to be maintainable. Rather, the focus is on submitting it fast and having it pass all tests. TopCoder contests, with their challenge phase (where participants review competitors' code and benefit from finding bugs in there), seems to particularly encourage writing obfuscated (and therefore unmaintainable) code.
For the same effect on classic hardware, you might want to look at https://sharemind.cyber.ee/.
Yes, I do have some friends in the project team.
