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…

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.

Nah, you still good bro as long as you are moving smoothly with the traffic.

What catches the trooper’s eye and gets you pulled over is doing all those lane changes if you want to be the fastest. That’s what is unsafe. Otherwise, they aren’t too concerned about the actual speed as long as the traffic is flowing smoothly.

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.

Well, beyond the sheer social resistance to the idea. Turns out everyone needs to agree it’s a great idea and almost no one did. Evidently humans are wired to the base12 time format far better.

The attempt at switching to base10 time quickly fell apart when people started notice that the the “time markers” were starting to drift. And at some point they finally figured out that what we call “noon” was going drift rather quickly to not happening until evening and therefore Monday was going to move to a different spot also. This is a very bad thing. Because any kind of calendaring system needs to be as consistent as possible. Noon must happen at the same point in the day every day or as close to it as it it can mathematically get. If it drifts to fast and far, then it’s a worthless marker for time. And decimal time has that problem in spades.

Now, no calendar system is perfect because the orbits of the planets in our solar system isn’t perfectly consistent. Sometimes the orbit of earth is a tiny bit faster or sometimes it’s a tiny bit slower. So we strive to get a close as we can but we still need to make adjustments. Turns out, all that math is really bloody hard.

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.

I paid $35 delivered from Russia. And honestly, I do not remember if that was a sale price or not because it’s been enough years ago now.Despite all the cheap quartz watches found in Walmart, $140 really isn’t all that much for a properly made manual wind watch these days. Even a plastic Timex will set you back nearly $120 for a quartz LCD with 24 hour display and only one choice of looks. So I probably wouldn’t consider the price out of line for the Komandirski with multiple choices available.

A Bespoke 24 hour mechanical movement would be quite the piece of horology art. A conversation started indeed.

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

Even the French figured out that decimalized time was stupid after a couple of years.

Which has added credence to the old saying that “The French follow no one. And no one follows the French.”

They don’t have to be expensive, though such watches are less popular for everyday use. In fact I’m wearing a Vostok Kommendurski with a 12/24 hour dial. When I was a medic, I needed to record all my times in 24hr format on my run reports. I think I paid $35US delivered from Russia 15 or so years ago.

And no extra gear is needed to make an analog watch/clock indicate 24 hour time. Time doesn’t change. You simple have one scale that reads from 12AM through 12PM and then at the next hour, (1PM) it simply gets renumbered to 13, 14, 15, 16 and so on until you reach 24 on the inside scale. Easy peasey.

But it is possible to build a watch/clock that the movement does move in 24 hour time and you would be correct it would a couple of extra gears to accomplish. But, it would also be a real pain to create a legible watch face with all those numbers on a reasonable sized watch. Far simpler and easier to print the two scales on the face and call it good.

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.
