I think you're just being silly, sorry.
That's why you send your metal parts to Shapeways etc. They don't need to look anything like being gun-related, it can be a generic-looking thing embedded in plastic or pushed over the plastic to reinforce said plastic. Maybe ceramic bullets would be a bit more suspicious, but I doubt the printing people care that much - yet.
Of course there are some laws that prohibit some of this. If the owner is a racist, there are non-discrimation laws that prohibit the owner for kicking you out just because you are black. I think we need non-discrimation laws for telecom clients.
Buy some firable modeling clay from the hobby shop... squeeze it into a mold... bake it in the oven. Bam... Bullet.
You're behind times. Just order them from any 3D printing service that prints ceramics. There's a few of those out there, bound to be more over time.
In 30 years we will probably have 3d printers printing in metal.
Not only we have them already, but common 3d printing services like Shapeways let you print in metal. You can also print in glazed ceramics, if you fancy literally your own cup of tea
And that's why, if you'd just go to a nearby hardware store, you'll find, oh horror of horrors, that the nail gun charges are available in multiple power levels. You pick one for the job at hand. There are charges that are good for driving nails into solid structural steel (think I-beam columns). Nail guns are not rifled, so they don't carry accurately, but a nail fired with the most powerful charge can go through a single layer of a hollow cement block wall and sure as hell it'll seriously injure anyone on the opposite side of it. All but the lowest powered nail gun charges will rip apart the bullet casing (usually the rim) if you're stupid enough to use them to reload regular ammo.
What's a projectile? I'm sure as heck a good old CRT is shooting out photons at the speed of light. I'm also sure that all radionuclides shoot off particles other than photons at speeds way over 300 fps. An electron moving at 300 fps has a rather laughable energy of 5E-8 eV. I don't think there are any small decay products with energies so may orders of magnitude below 1eV.
So, where do we draw a line between what's machine instructions and what isn't? That's where the slippery slope lies. I don't think there'd be much of a problem in printing out a set of usual-looking human-readable plans, and having an image processing system designed that can read those plans, convert them into a solid model, and have it printed out. Heck, I wouldn't be surprised if someone was coding one right now out of spite. It'd make a nice Ph.D. if it was a reasonably general-purpose system.
That's understood, but I don't get the point of doing unsafe work of any kind on your own place. I thought the whole point of doing it yourself is to do it at least with due care. Yes, sometimes it may not look as pretty as something done by a long-time pro, but it's supposed to be safe and long-lasting. I'm sure my tiling isn't as perfectly even as someone who has done it thousands of times, but sure as heck it's at least level, decoupled from the subfloor, very solid and is not supposed to crack in my lifetime. Same goes for plumbing, electrical, or really any other trade I'd do on my home. For major things I do get permits and have the inspections pass without problems. In the U.S., laws are free, thus you can get all of the relevant codes for free. Europe sucks in that regards, I'm sure Australia suffered from European braindamage in that respect as well.
It would be way too complex, logistically, to have it shipped by road directly. It pretty much blocks one direction of traffic on a divided highway. It will travel probably a 100 miles or so over land, and the rest by barge - down the east coast, and up the Mississippi River.
Well, that's if the wires are "short", like in a typical single-family home. For long runs, NEC has you calculate the voltage drop and mitigate excessive voltage drop by going to a larger wire size. But this has nothing to do with overloads - the larger wire does not automatically let you install a larger breaker!
So, this vs. taking the vaccine and its horrible risks. I think I'd rather risk it, you know
Anything DIN-rail mounted obviously is out of scope, you don't put DIN rails in an electrical junction box in the wall. The spring-loaded terminals are a complete joke as well, they usually have a couple of tiny points of contact and I personally wouldn't use them for anything but signal wiring. When you have a twisted wire nut, the wires are in contact over a length of a centimeter or more directly wire-to-wire, and they are all also in contact with the spring material in the wire nut itself. And who the heck uses stranded wire inside the wall?
HPV is preventable in behavior? Pray tell, how? LOL.
I think that the problem we have is only tangential to the vaccines. Our communication skills demonstrably have not evolved to rationally cope with ubiquitous access to communications. People get quite irrational and their selection biases show simply because they see an "OMG" post on Facebook or an alarmist segment on their evening news.
