For the QR Code Shadowblock in the OP, I wonder how he dealt with supporting all the structures within, but not all combinations of pixels on each face will work. Maybe he just played with it and rotated the QR codes to find a combination that will work.
I have thought about a QR Code Quine, where the QU Code contains an OpenSCAD file that is a model of the QR Code. However, I wasn't sure exactly how to tackle that, since the QR Code decoder is non-trivial.

It's actually not too hard to do with OpenSCAD or any other modeling tool that allows you to do intersections. So I've tried other three letter acronyms: https://cubehero.com/physibles/iamwil/shadowblock/print
