Lol, do you realize that regular 2D printer manufacturers have mandates for embedding codes in the prints so that they can be traced?

Or that Photoshop and photo editing software has mandated counterfeit bill detection features in it?

It doesn’t completely invalidate all of your points, but the idea is not as crazy or unprecedented as a hammer with anti murder technology. Hell even just basic cap guns have to have an orange tip.

As long as gun nuts kept insisting on designing and printing guns, this was inevitably going to happen. Like what the fuck did they think the end result of designing and distributing murder machines online was going to be?? Did they really think everyone, in every jurisdiction and country around the world, was going to agree with their dumbass Republican interpretation of the 2nd amendment?
