It would appear that Bambo Lab had made an almost Macintosh-type leap with their new A1 3D Printer.
I can't say that I have a need for one. But these are becoming as inexpensive as desktop printers and nearly as easy to use if you use the various pre-made models that are out there. Making your own, of course, takes a little more thought and effort.

I'm tempted to buy the Bambu Lab A1 Mini for $300.00. But I have to ask myself if I will really use it. So far the answer is "no." But I like learning about the process, because it's a process I've heard a lot about. Whether I would use it or not, this particular machine would make a great hobby machine...just to mess around with, as it were. And one of the tools to create 3D objects for use in 3D printing is Tinkercad by Autodesk (who also make the more powerful Fushion 360 (which also has a free version, although I haven't tried it). You can find a five-part set of introductory tutorials here. Yes, it's basic but I think there's a lot of power in it. And it's certainly understandable and a good place to start.

What kind of stuff could you make with this machine?

To be quite honest (to set apart from the times I am dishonest), 90% of the stuff people are making with 3D printers is trinkets-and-junk. Kitsch crap of the worst type (although I'm sure they have fun creating this crap).
I don't need to print a dragon egg. I don't need to make little soldiers or really cheap-looking Christmas ornaments. I don't need to make little frogs or duckies. And when you remove this 90% of the equation, one is left with:
However, Bryan noted just today that if I got a 3D printer, he has a job for me. He wants me to create some device that will lift up one of his long tables by about six inches. And they do make "leg extenders" for tables. And we actually have four of those working well under another of these "banquet" style tables. But this other one has more peculiar legs and they wouldn't work on it.
Plus, although this would take some time, I thought about piecing together a Stepford Wife. With AI going the way it is, it should be possible to fashion something like that.
But, seriously, I'm not sure how many make-work projects I could come up with. But I'm sure I could come up with a few.

I was thinking this might be the case. Sure, you could come up with a few useful items, as you noted with your table lifter, but I wondered how many items of value you could produce.

Well, the truth is, it would be a bit of an answer looking for a problem….aka a "hobby." But in practical terms, I can't justify it. But it would sort of also be a Christmas present to myself.
But I do like learning new software. Aspects of designing in 3D are very similar to using Adobe Illustrator (a primarily 2D drawing program) which I've used since about 1988. 3D is sort of just 2D with the 2D drawings being extended or extruded, as they call it. In fact, one of the first tests I did with the Tinkercad 3D software was taking a logo I designed in Illustrator and moving it into Tinkercad. It worked great.
3D CAD design, of course, shoots all the way up in the learning curve to truly stratospheric heights in terms of what you can design. But I would not be designing jet engines. More likely it would be simple brackets, parts, and such...oh, aside from the Stepford Wife, although that would be more of a long-term projects.
We'll see.

For the last couple of weeks I've been learning the various software involved in 3D printing. It's nice that you can use the Bambu "slicer" software even without the printer.
"Slicer" software is roughly the equivalent of a computer print dialogue box. In that software you set up where to print, how large, which face to set on the bottom plate, what quality, and sort of the basic things you might do (if you really dig down) in a print dialogue when printing to a laser printer.
There are some advanced features as well in the "slicer" software that allows you to manually color things (if you have a 3D printer equipped with several different spools of filament to choose from).
Bambu's "sliver" software is called Bambu Studio. The other piece of the puzzle is the software to actual create the 3D models. I've mentioned before Tinkercad and Fusion 360. The former is free and the later has a free version for hobbyists. Because they are both (now) owned by the same company, you can use them in conjunction with each other. For instance, you can create something in Tinkercad and then use some of the more advanced features in Fusion 360 to edit it.
Either I'm slow or YouTube teachers are quite willing, but often lacking the ability to teach concepts in a clear and coherent way. Let's give credence to both, for sure. But, good golly, although you can't really complain about someone offering free advice in a YouTube video, it can be nut-driving how confusing these videos can be sometimes. I mean really bizarrely and unnecessarily confusing.
I like to think of myself as a good teacher. Perhaps this is true if only because I need things explained in coherent steps with an overall rationale or conception of the paradigm in play. That is, you need to know not only what to do but why to do it. I'm sure Brother Artler understands this as I imagine he was an excellent teacher.
But I'm nowhere near buying a 3D printer. However, with some of the skills I've learned, I would certainly be able to create my own 3D printer file and use some online site to print it out. I'm just not sure I would use a 3D printer regularly enough to justify buying one. Still, as much as I liked stuff like the Vac-U-Form and Thingmaker (with PlastiGoop) when I was a kid, this stuff is sort of right up my alley.

I haven't purchased a 3D printer yet. But I have continued learning the 3D programs, particularly Fusion 350. My brain hasn't worked this hard since trying to understand the female mind in regards to letting men who claim to be women use their locker room. The above is a relatively simple part but probably represents the most complicated thing I'd ever need or want to make for myself. There are two main challenges to overcome: 1) The sheer depth and obscurity of the Fusion 360 program. 2) The madcap (but well-meaning) YouTube tutorials that jump around, make mistakes, start over, skip vital instructions, and just generally don't actually explain much of the time what they are doing or have actually done. And, in many videos, the videos seem to jump or drop frames so that you don't see what menu was chosen and things like that. And it's definitely not my computer that is the problem. When you, from time to time, are yelling (literally) at the screen at these guys for making an already difficult task more difficult, then the saying "You get what you pay for" comes to mind. All these tutorials are free, of course. But sometimes it's just amazing. I think many of these yutes are strung up on caffeine or something. They go so fast and are so fiddly with mouse motions and all.

Well, I pulled the trigger and bought the $300 Bambu Labs A1 Mini. After putting in 6 or 7 weeks of studying 3D modeling, we can at least say this isn't an impulse buy. I spend a lot of time learning Fusion 360 as well as the Bambu Labs "slicing" software (and Tinkercad as well). My version of fun. It's smaller than I thought...or smaller than pictured, although I was well aware of the actual printing dimensions which were fine with me. It takes up very little room, about 15" by 20". It sits unobtrusively on the end of a fairly massive table/filing cabinet combination. It was easy enough to set up. I have run into a problem with the filament getting tangled on the spool which causes the printer to jam. This has happened about 5 times and I've emailed the manufacturer and said basically, "Give me a solution or I'm sending it back." Meanwhile I'm looking for my own solution. I may have found something that will hold the reels better and divvy out the filament (via bearings...sold separately) with less friction. In the meantime, I printed a sample that came on an included SD card. It does a good job. And it's quieter than I expected. I have it printing something now and the noise level is quite livable. But certainly you can hear it. I think the difference that it's not an irritating sound, if you know what I mean. And one of the tutorials I found online allowed me to design something that is practical. It's a small drawer that attaches (via double-stick tape) to the bottom of a shelf. I have just the place for it. It's a start. I'll trying printing that out tomorrow.

As my brother said. I guy's gotta have a hobby. But it's not just a hobby. And rather than threatening little girls with my creation, I'm saving the planet. The filament type mostly used in 3D printing is called " PLA." It's biodegradable and (somehow) "sustainable," whateverthehell that means. Now, your task today is to use "ring-opening polymerizations" in a sentence. But, interestingly, although (I guess) PLA is derived from plant materials, this stuff is amazingly strong. And the odor of it is only very slight, although other materials for PLA printing I guess can and do produce stronger fumes.

The glowing runes, which could be read for a moment after exposing the Ring of Power in Gollum's possession to intense heat, were the result of ring-opening polymerizations which were powerful, yet transitory in nature.

Very good. Let me try:
On Valentine's Day, Kevin and Tristan found time alone to engage in ring-opening polymerizations.

end up making one of these. The history of the Golem is Eastern Europe, mostly the Ukraine Pale and verry Jewish. Please don't make one I'm not sure your area has enough Hasids to counter a true Golum. en.wikipedia.org/wiki/Golem

I think I figured out my jamming issue. And it had nothing to do with ring-opening polymerization. It was User Error.
When you first unpack the reel full of filament, everything is taped down. So you remove the tape and the loose end sort of "sproings" now that it's free. No problem. I found the end of it
But what had happened is that it had looped under another strand. And so every once in a while it would bind. Once I figured this out (with online help), I fixed the kink and haven't had a problem since.
There once was a Jewish Golem And no one could ever control 'em So instead of mud and clay They used strands of PLA He's now a 3D monster, I told 'em
