I assume they add a custom wiggle to the print head so the "serial" is embedded into the plastic everywhere inside and out.

Exactly. So if that wiggle gets sanded off you have effectively anonymized your part

The wiggle isn't only on the surface. I'd bet it is everywhere except for the surface or users would complain about defects. So if you sand the surface, the forensics slices it in half and reads the wiggle that is embedded everywhere inside.

Ha. I'll bet you're 100% correct.

When the wiggle is inside the part the part will be gone after sanding it off.
