Fair point it’s illegal in your country. So if you are going to restrict plans/blueprints/3D files (nigh impossible this digital age), then would you also go as far to restrict access to people owning milling machines, CNC machines, and the like? People like my grandpa could make just about anything out of metal. Any half way skilled machinist could make at the least a basic firearm, even with out plans. After all, if the mere possession of plans should be regulated as it makes things too easy to break the law, wouldn’t the actual equipment needed be even more dangerous and thus require additional regulation?
