Re: Man 3D prints face grenade, is saved by police
I believe they put the serial number on the lower BECAUSE it's so critical to the proper operation of the thing. Tagging linchpin parts makes it harder to switch out the tags since you run the risk of breaking the thing in attempting a swap. Cars adopt a different strategy: placing the same tag in multiple places, including INSIDE places that can't be reached after assembly without making obvious cut-ups.
