I picked up a Creality Otter 3D scanner a while back. I just opened it yesterday and tried it out. The scan software didn't work on my
everyday CAD/CAM design computer. Its an older i7 with an Intel 4600
video card that works just fine for 3d modeling with 64 bit ViaCAD, and
has no issues keeping up with CamBam and ViaCAD simultaneously.

Fortunately, I had a newer computer I picked up early last year with
some kind of hotrod video card. With all the things going on in my life
I just didn't bother with it. My computer is working, and it will take
a day or two to install and configure everything on a new computer. The
new machine is a lot faster i9 with a smoking video card and more
memory. This morning, I put it on a desktop, hooked it, and installed
the Creality Scan software. I didn't even bother to calibrate the
scanner. As soon as it started I went straight to a scan.

I don't know if it will be useful, but I'll have fun finding out. First
test scan below. I didn't change any of the defaults.

Yes its is metalworking related. I hope to be able to scan customer's Frankenstein's creations and cut molds for them in some cases. The
accuracy is a couple thousands at best, but that's good enough for a
rubber worm. In most cases it will probably still be easier to just 3D
model the positive.

Yeah, I am behind the curve here, but until recently even mediocre but
reliable 3D scanning was out of my price range. My son has been doing
3D printing for a while, but I rarely find it worth while. Atleast
compared to the machines my son uses I can machine most parts far faster
than I could print them. He, however, might try to "borrow" my scanner
to 3D print some stuff.

More metalworking content.

One of the vehicles I have "extra" is a Hyundai Kona I bought new for my
mom when my dad was in the hospital recovering from having a brain tumor removed. They didn't have a 100% reliable set of wheels and there was a
reason (at the time) I wanted my mom to have a car that was HERS.
Mostly I wanted them to have a reliable grocery getter that my dad
couldn't turn in to a handyman service vehicle. She gave up her license
last year so, I have it back. I'd looked up the tow rating on line, and
I was pleasantly surprised to see it had one, but when I looked int he
owners manual it said, "not recommended for towing." I wrote it off for
a while, but than I ran across several conversation on various car
forums, and Reddit. Its seems ALL the Konas trims sold in Europe and in Australia have "some" tow rating. Only in the US do they say, "not
recommended for towing." Of course Curt makes a hitch for it, so I
bought one. I've been spending the afternoon installing it. It seems
pretty simple, but you have to drag the bolts through the inside of the
unibody frame member tube and poke them out from the inside. Yeah, its
as goofy as it sounds. I've got three bolts poked out and nuts on them.
Now to go do the other three. The lowest rating I found was 620KG on
foreign models, so I figure a self imposed max of 1200-1500 lbs, shift manually, and don't run speed limit on the freeway if its loaded or
climbing hills.

"Fascinating", said Spock.

Many craft fair and flea market vendors here sell 3D printed monsters
etc from Thingiverse. One told me the people who profit most aren't the sellers but those who license the designs. There's hardly ever a useful
and practical item in their displays.

Almost everything I dream up can be made on a lathe or mill, of course I don't often dream of marine invertebrates, beyond an occasional
Architeuthis. My doctor's idea of up-the-system individuality is socks
with a Kraken on them, and I was at a beach the day the remains of one
washed ashore, but too far away to see that the small group of people
was looking down at something. https://en.m.wikipedia.org/wiki/File:Squid_plum_island.gif

I bought some bake-hardening polymer clay for free-form shapes or
impressions but rarely use it, I need the strength of metal.

SCULPY! Lots of tackle makers use the stuff to make masters. Others
hand carve, and yet others Frankenstien pieces and piece together with a
hot knife. My only "practical" use for 3D printing I came up with was
to print master molds to make silicone molds to cast resin work pieces. Catalyzed resin is way tougher than most (99.999%) 3D print resins and
plastics filament prints.

The current project is a draw plate or roller pair to make replacement
yagi TV antenna elements from aluminum flashing. I can almost form the open-seam tubes around a transfer punch with a soft hammer and anvil
after roughing the curve on the press brake. They are fragile enough to
not damage the shingles when blown down.

And to think we all made fun of Radio Shack back in the day...
