FreeCAD and OpenSCAD. FreeCAD is steadily getting better and better.

I was specifically called back to be asked about this. It felt so weird because in my country this is not a common question

This vastly depends on the field you are talking about.

There are absolutely things that are worth doing yourself, so that when they inevitably break you can fix them.

And there are also other things that are absolutely better bought or contracted...

In the end imo it gets down to time, money, and how many times are you going to need to maintain or replace the thing in your lifetime.

Would fit right in in a cyberpunk setting.

To add to this, it is the general term for all non-firearms: so it covers also bludgeons and anything else you swing by hand.

My friend, you are technically correct.

Which is the best kind of correct.

I think that it's a reasonable license for them to protect their business while continuing to provide full access to the community. The single user would still be able to modify or even build their own clone, but a private company would not be able to just sell a copy.

In an ideal world where money did not exist this would be detrimental to innovation, but in the real world Prusa needs to make money to stay in business. And considering their competitors, I would much prefer them to stay in the business and as much ahead of the competition as possible.

I've had my old macbook for twelve years and the whole time it held up punching well above its spec range and running heavy loads. I customized it deeply. Never had to reformat, which instead I had to do more or less once a year on my previous Windows computers. Whenever I asked it to jump it asked how high. I don't think longevity argument has merit, at least for computers.

Sorry, I formulated that badly. They used to be legal up until the 70s or 80s.

Of course, I never intended to imply that a plastic knife would not be dangerous

If you were to bring a letter opener to school and sell it to your friends you would still get a nice meeting with the police. The existence of the journal article is more related to the fact that a kid was stabbed to death in school last week, than to the fact that a dumb kid did something stupid and marginally related to his 3d printer.

Afaik, all one hand operation deployment knives are illegal to carry in Italy. Ballisongs/butterfly knives included.

I'm not sure if there are special licenses that would allow you to carry them.
