As a non realistic version, have you played timber born? It’s about beavers making dams and towns, but very much not realistic.

I think it’s stupider than that. They have no idea how a handmade gun could be built without a 3d printer. They probably have zero clue what a 3d printer actually can and cannot do, and I’d bet most politicians have never seen one or bothered to understand it before regulating it. Their sole exposure is a few loud people who also do not understand anything about guns or 3d printers, and confuse that lack of understanding with definitive proof that it is evil and should be banned.
