3D printing software? [tech]

I want a widget that doesn't exist so I might be stuck designing it for 3D printing. I have never done this before. For design software, I gather both Onshape and TinkerCAD are available for free. Anybody with experience have opinions which I should start with? I have never used any CAD program before, but am not new to drafting. OTOH my drafting experience was all about 40 years ago. Open to other suggestions available for the Mac for free.

Also, I don't have my own 3D printer, so I'll be availing myself of various public-access options. But this means the iterative design feedback loop will be irritatingly protracted. Also I might have to pay money for each go round, so I'd like to minimize that. Also I am still disabled and not able to spend a lot of time in a makerspace. But I am a complete n00b to 3D printing and have zero idea what I'm doing. Does anybody have any recommendations for good educational references online about how to design for 3D printing so your widget is more likely to come out right the first or at least third time? By which I mean both print right and also function like you wanted – I know basically nothing about working with the material(s) and how they behave and what the various options are, while the widget I want to make will be functional not ornamental and have like tolerances and affordances and stuff. So finding a way to get those clues without hands-on experience, or at least minimizing the hands-on experience would be superb.

Saw this, blew my mind, thought I'd share. Behold, Lençóis Maranhenses:



2025 Oct 28: PBS Terra [pbsterra on YT]: It Looks Like a Desert. But It Has Thousands of Lakes

When I heard in the video how big it was, I turned on satellite view in Google Maps and popped "Lençóis Maranhenses" into the search bar:

Getting a head of things [gastronomy]

The Bostoniensis household's last grocery order included some cucumbers but the delivery service mystifyingly substituted for them a head of cabbage. They were very apologetic when Mr B called to complain, and refunded us the price of the cabbage, so now it's a free cabbage. But it's still here taking up a remarkably large volume of space in our fridge, what with the spherical thing, and it's a week before Thanksgiving.

Cooking a cabbage was not on our plans for this week. But throwing out a perfectly good cabbage seems sad. And I have been complaining about not getting enough veggies to eat. So.

Anybody have a very delicious recipe for cabbage that conforms to the following parameters?:

• Cooked. No raw cabbage.

• Really, really low effort. I am resigned to having to chop the cabbage itself, but maybe minimal other chopping of other veggies or meats. Something where the actual cooking isn't too fussy.

• Not haluski. We love haluski. We have most of the ingredients for haluski. We do not have the time or energy for taking on a project like haluski.

• Not stuffed cabbage. The kind with ground beef and tomato sauce. Neither of us likes it. Possibly because we don't like the taste of cabbage in tomato sauce.

• Not corned beef and cabbage. We love corned beef and cabbage but omg have you seen the price of brisket.

• Relately, maybe no stewing or slow cooking? The smell of slow cooking the corned beef and cabbage is dire, and we don't want to have to flush air we paid to heat. Maybe it would be okay if more heavily seasoned.

• Gotta mostly be cabbage. We have a lot of cabbage to get through.

We like spicy, though it's not required; no cilantro, and probably no coconut. Main dish or side, with meat or without.

Edit: Okay, maybe we'll just buy more cabbages. I am very excited by this harvest of recipes.

Hey, Americans and other people stuck in the American healthcare system. It's open enrollment on the state exchanges, and possibly through your employer, so I wanted to give you a little heads up about preventive care and shopping for a health insurance plan.

I've noticed from time to time various health insurance companies advertising themselves to consumers by boasting that their health plans focus on covering preventive care. Maybe they lay a spiel on you about how they believe in keeping you healthy rather than trying to fix problems after they happen. Maybe they point out in big letters "PREVENTIVE CARE 100% FREE" or "NO CO-PAYS FOR PREVENTIVE CARE".

When you come across a health insurance product advertised this way, promoted for its coverage of preventive health, I propose you should think of that as a bad thing.

Why? Do I think preventive medicine is a bad thing? Yes, actually, but that's a topic for another post. For purposes of this post, no, preventive medicine is great.

It's just that it's illegal for them not to cover preventive care 100% with no copays or other cost-sharing.

Yeah, thanks to the Obamacare law, the ACA, it's literally illegal for a health plan to be sold on the exchanges if it doesn't cover preventive care 100% with no cost-sharing, and while there are rare exceptions, it's also basically illegal for an employer to offer a health plan that doesn't cover preventive care.

They can't not, and neither can any of their competitors.

So any health plan that's bragging on covering preventive care?.... Read more [2,270 words] )
