Sometimes you have a run in with a customer that ain’t worth having-- no matter how much money they pay.

That’s Best Korea^TM to you!

I have designed several 3D printed firearms related items.

I designed and printed shims for my Winchester SX4 shotgun, (Winchester claimed they couldn’t design them and make them work), and I uploaded the .stls for the set so other shooters could make their guns fit better so they could hit targets better.

I also designed a 3D printed EZLoader for a SIG P365 pistol. Those 12 round double stack single feed magazines are nearly impossible to load without one. And I felt the commercial ones that cost $40 or more were too expensive. So I designed something simpler and cheaper you can make at home for yourself.

These designs came about because I discussed problems with other shooters on several different shooting forums. Does that make me a criminal? While neither of my designs are anything like a Glock switch, no one knows just how far the law could be stretched if wanted. And one thing everyone knows is just how ignorant police are about laws. Not to mention just how impossible it would be for the state of New York to police the entire internet in search of such files and discussions. They can’t even stop you from downloading a pirated copy of your favorite video game. This proposed law is more feel good theater than anything that can be considered effective.

And if what I could do with my 3D printer scares people, just imagine what I can do with my metal lathe, mill, and welders…

Slide over a bit, I’ll join you…

I looked PHA up. Color Fab offers some at a fairly reasonable price, but limited colors. It seems an interesting choice for printing. I do like the heat resistance of >120C. The printing temp range is low and pretty narrow and needs hair spray. I wonder if it’s comparable with PEI print sheets.

But it still has a price hard time competing with the $11US per kilo of PLA brands like eSun.

Gemini has popped up pnce since it became a thing. I simply clicked no and it’s gone away. So hopefully it stays away.

There are firearms related .stl’s that can be found, but they are accessories rather than the actual parts that make a firearm function. But there are forums that do discuss and build 3D printed firearms that can be found with some searching.

I’ve done a couple of designs, shims for a Winchester SX4 shotgun to fit several guns to their owners for target shooting and hunting. And an easy loader for my P365XL. That 12 round double stack single feed clown car of a magazine is hard to load without it. But I haven’t bothered to publish either design and I have never wanted to either.

Congtrats! you just made a pipe bomb! And one that isn’t as good as a steel pipe You do understand that PVC pipe would not be able to contain the pressure of even the most anemic cartridge don’t you? Even a 1" schedule 80 PVC can only contain up to 520PSI @ 73F. Modern Cartridges easily generate 12,500PSI for a light shotgun target load of birdshot.

So, I don’t know what 3/4’s of those pictographs on the chart mean. Am I in the wrong place?

A simple google search, (which YOU could have done yourself), shows it’s abut 1 in 1.5 million miles driven per accident with FSD vs 1 in 700,000 miles driven for mechanical cars. I’m no Teslastan, (I think they are over priced and deliberately for rich people only), but that’s an improvement, a noticeable improvement.

And as a an old retired medic who has done his share of car accidents over nearly 20 years-- Yes, yes humans swerve off of perfectly straight roads and hit trees and anything else in the way also. And do so at a higher rate.

You are trying to judge the self driving feature in a vacuum. And you can’t do that. You need to compare it to any alternatives. And for automotive travel, the alternative to FSD is to continue to have everyone drive manually. Turns out, most clowns doing that are statistically worse at it than even FSD, (as bad as it is). So, FSD doesn’t need to be perfect-- it just needs to be a bit better than what the average driver can do driving manually. And the last time I saw anything about that, FSD was that “bit better” than you statistically.

FSD isn’t perfect. No such system will ever be perfect. But, the goal isn’t perfect, it just needs to be better than you.

It’s part of a joint for the handle of an electric snowblower I have. It’s a cool looking part for sure, but it was easy to recreate as a model to print.

But after breaking the original injection molded glass re-enforced nylon and 3 other home printed parts, I redesigned the joint to be a single piece solid part. So while I can’t fold the handle down for storage, it no longer breaks.

Or if you can scrounge up a guitar string, you can simply make your own coil spring from scratch.

All work done in FreeCad.

My favorite personally reverse engineered part

And a favorite design I use every day a holder for my loose tea strainer to catch draining water

I had a 486DX running DOS for writing and editing CAM programs for CNC mills, lathes, pipe bender, and a laser cutter. And for funsies, an even older Macintosh that booted from a 5 1/4" floppy that ran a CMM, (co-ordinate measuring machine). And the software for the CMM ran from another 5 1/4" floppy.

This was about 2017 before I retired as a toolmaker.

It would be interesting to see a picture of daddy too. I wonder what traits she got from him.

Well, you might be half ways there. And one should never halfass something, always whole ass it.

Yep. the Qt wars were real. And one needed to be careful about reveling your KDE use because you would get flamed with hatred.

Obviously Tarantino was involved. A little foot fetish never hurt nobody-- right? Right???

Do you want to pay for the heating and cooling of a bunch of those tanks out of your pocket? Or even the cost of upkeep to keep the tanks clean?
