Some sort of wire recorder? The teeth of the 3d printer ‘driver’ (sorry lost on the terminology here) already make an imprint on the filament, maybe it could be made intentional

Wow! Now that's some outside the box thinking. That even seems to suggest that "watermarking" a print (or a small, hard to notice part of a print) would be possible.
I also think you could get denser storage that way? I guess depending upon how thick the "wire" is? But it's an interesting idea for both just printing the wire, and for the driver-teeth imprinting, separately. Very cool!
Not sure how it will survive extrusion. But yeah, the wire is a cylinder so you can ‘imprint’ multple ‘sides’. Another idea, some form of anti temper encryption like little particles (flock) inside the filament (like those colored rice anti temper methods)
