Aren't they already doing that due to their hysteria over "ghost" guns?

They can try, but the parts that make up a printer are used in tons of other applications. It isn't hard to build one from scratch.

And just like age verification it's useless because one can build a 3d printer out of an old VCR and a hot glue gun.

They're already trying that in New York and California, unfortunately. "Any 3D printer capable of printing parts for firearms" was the verbage, from what I recall.

They already are over 3d guns, this will send them ballistic. They want every printer to keep a record of everything they've printed. Model legislation, I think CA tried and so far failed to pass it.

3D printers are even less useful here though. The rocket bit can be replaced with a cardboard tube and some balsa fins. The important parts are the active control and circuitry.

But I guess logic doesn't really enter into the conversation anyway.

LOL. Like they "ban" some guns?.

Printers are not hard to assemble from parts.

I wonder if there is some archive or torrent for STL files, like an archive of thingiverse or something. Would be nice to archive that just in case.
