The lathe & knee mill thing is being nibbled away under the ‘ghost gun’ fears - yes 80% is a weird line in the sand but we have to define it somewhere between “non-descript block of metal” to “legally now a gun”. Not sure how that’s going to survive legal test, the law there needs a refresh tbh

I’m really more surprised to see 3D printing not being targeted/trolled by copyright and IP lawyers. There was some limited activity with Games Workshop and people scanning wargaming miniatures to cheaply 3D print instead of paying (exorbitant) retail prices, but hasn’t gone far beyond banning non-official minions at official events
