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

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.

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.

Afaik, all single hand operation deployment knives are illegal in Italy. It’s somewhat of a nonsensical rule when there are teenagers stabbing themselves with kitchen knives, but still…

It’s not because they are 3d printed. He was distributing them at school! That is the problem.

If he were to file down toothbrushes and do the same he would still be arrested and his files confiscated.

Wow, that is absolutely mind-blowing. I never expected it to work with such complex designs! Mind sharing some tips or examples of how you accomplished this? I’m really curious about the notes around the ring

It is getting better, but I still get crashes in 1.0. I feel like there are some specific tools and features that are a lot more prone to crashes and others that are quite solid. I had crashes in particular with the thickness tool and some joins in the assembly workbench.

Supports for some plastic led strips, to mount them to the wall.

I agree but with a caveat: openscad still requires people to understand code. It is still. A whole new skillset that not everyone is going to want to learn.

I agree on freecad! Version 1.0 made it a lot more usable. I moved away from F360 some time ago and now that freecad is more useful it has comfortably replaced 90% of my workflow. It is still a bit clunky, but can get you there.
