would you believe me if I said I meant bowler cap? or maybe a top hat?

(and this is where I find out that Hannah Montana linux uses a top hat for a logo, lol)

<chuckles> We use dnf here.

<tips hat and runs>

and that is why standard sizes exist. The solution then, is to get every one on standardized sizing so the parts work.

The problems are that now somebody needs to have and maintain a printer. (I presume FDM, but resin or something would be more useful.) even then, the production is limited, and you’re still having to source filament or whatever, as well as the parts necessary to maintain it. These parts are all more complicated than PVC pipe fittings are. (and depending on where we’re talking, may not even be available for a variety of reasons.)

and when the part fails (as all things eventually do,) you’re going to be right back where you started. You might be able to get another custom part printed. if the guy happens to still be around and availible.

Granted, the people running the study or setting up the open source fittings probably don’t have the money to encourage people to replace their plumbing, but that’s the solution that won’t see us right back at the problem in a few years. or less.

The researchers believe using a parametric-driven method for local, on-demand 3D printing of customized fittings will unlock more efficient water management.

there’s a whole lot of buzzwords there. if the current system can’t be fixed becuse there’s no parts (pipe fitting, and pipes,) to replace the leaky bits, then how exactly do you expect them to source a 3 d printer and filament? More to the point… FDM prints themselves are prone to leaking, from a myriad of issues.

I don’t think 3d printing the pipe fittings is the answer here.

that said, it’s cool and fun all the same.

theoretically? yes.

several problems.

Food dehydrators typically apply heat as well, and sometimes significantly higher than a filament dryer.

Then there’s the cleaning and bacterial contamiation issues- food dehydrators are made to be easily cleaned so as to prevent bacteria doing nasty things to you.

Then there’s the various resins and solvents that sometimes off gas becoming toxic.

Microplastics is far down the list if you’re desperate, but it’s there too.

but otherwise, they’re still basically the same device A heater (maybe) pushing warm(ish) air over something.

protests are happening everywhere, in every state, though they’re mostly small. the news isn’t covering a lot of them because there’s no rioters and the news can’t push a narrative that people hate trump.

Unless you happen to live fairly close… which is fairly not likely…. So you drive to a rally point or someplace near some transit (or with plausible deniability,) etc. to get in.

Or just conceal your plates and don’t drive something flashy,

there is something to be said about being connected to others. particularly for protests that move around or so you can let people know you’re driving home etc vs locked up for bullshit.

it’s also convenient as a form of souseveillance. Just remember pictures and video are evidence, that cuts both ways; especially in the face of cops being excessive.

(opps, wrong person,)

Not really.

Most new phones use other identifiers. You might be able to buy very cheap prepaid phones or cards for them, but they’re going away from swappable sims.

For most carriers, if you occasionally want to swap to a different device it’s just a matter of going to your account online and swapping it (for example, travel. It’s safer to use a clean device rather than your normal phone. Both for border crossings and everything else.)

I highly recommend graphene.

And for anyone going to a protest to get a cheap burner and flash graphene, then leave your normal phone at home. You can swap phones on your plan pretty easily.

Alternatively, for the very paranoid, go set up a prepaid and anon line and move your device there. Pay cash for the card and set it up online at a public library.

Especially if you’re planning on a little civil disobedience.

Just a reminder, if police think something is about to go down, they’ll spoof the tower and collect device information… including things like phone numbers so if your suddenly changing behavior to go somewhere and do something the fascists dickfucks in office won’t like… best be paranoid.

A second device will still at least keep them from getting all your personal shit. And seriously, Don’t just turn off your normal phone. Leave it at home.

Yes. But you have to spoof your browser credentials.

reverse engineering a solution isn’t as easy as just a few pictures. we would basically need physical access to replicate the critical dimensions and then feed it into something, print the test fit pieces and double checking fit before coming to a final design.

you’re unlikely to find an .stl beause basically every laptop is going to be different. This really is something you need to design yourself.

plenty of us saw this coming.

it’s why we don’t have bambus.

The existence of rainbow filament doesn’t negate what I said.

Especially considering, that making it yourself would allow you to customize the pattern significantly.

I prefer the somewhat more random nature of the homemade version. (Length/size of the color bands, which colors/filaments, order and patterning.)

You’ll find in life there are frequently many paths to the same ends.

So?

The way around that is milling in fins on either end, this would basically act like a heat break between the hot and cold ends of a printer.

Or just load the thing and then turn it on. It heats up, melts the plastic and then immediately shuts off. It would take 30 seconds, maybe.

The only reason practical engineering is more fun than over engineering is that things actually work.

But, eh, over engineering things is fun too- at least as a thought problem. If OP thinks some leftover Bowden tubing is too expensive, though… it’s only a thought problem…

If you could get economies of scale working, you might be able to hawk it on Amazon for 20 bucks, though. (Not that I’d ever… that sounds like a desk fire waiting to happen…)

• Benchy approves.

So, hypothetically, could you use a ball end mill with a 1.75mm diameter? Then mill the channel across two halves?

Basically, something like a halved heater block. Put a cartridge heater on one side, thermistor on the other, take it up to a melt temp and shut off. (Maybe add some cooling fins beyond the intended melt zone?)

Also, have regrets because this is more expensive than the boden tube method.
