I understand the intent, but feel that there are so many other loopholes that put much worse weapons on the street than a printer. Besides, my prints can barely sustain normal use, much less a bullet being fired from them. I would think that this is more of a risk to the person holding the gun than who it’s pointing at.
The thing is, banning guns is giving them an inch. NYC is already trying to grab 3d printers. Hell the ATF infamously made showlaces into unregistered machine guns, and a felony. https://www.everydaynodaysoff.com/2010/01/25/shoestring-machine-gun/
And abroad, the UK went after knives.
Never think they’ll stop at guns, because they won’t. Its slippery slope, but that slope is supported by historical evidence.
