3D-printed book turns its own G-code into raised lettering

I'm sure the idea here was a physical quine, although since it only contains 2.5% of its own G-code it's not really a quine, any more than a "Hello World" program is a quine since the string "Hello World" is in the program text. It would be trivial to generate something like this depending on which part of the G-code you pick.

Is anyone else confused by thier cookie consent banner? The switches start out gray and become black when toggled. which position means consent? It feels intentionally misleading.

> Manual contains only 2.5 percent of its own G-code in its first version. That low figure is part of the point. Current FFF 3D printing resolution and text scale place limits on how much code can fit onto the object while also describing the volume of the object itself. A fully self-contained version would enter an endless loop, since every printed mark would add more data to be described.

The fact that quines exist means that it must be possible to print a fully self-describing book of this sort, though it's possible that you'd require a more expressive language.
