There are two ways to do that, actually. You can right click on a cell and use its properties window to add an alias, too. The alias box in the upper right is fairly new-ish, I think. I don’t remember when it was added, but I seem to recall pre version 0.2 you had to do it the long way, which was both A) hidden, and B) a faff.

I never knew such a thing existed, but I’ll look into it.
I don’t touch the workbenches much. Up until now I’ve never found a use for them, and most of the ones I’ve tried on a lark tended to be buggy enough to be more trouble than they’re worth.

- Comment on Experts say high food prices are here to stay. Here's why 2 weeks ago:
Not a single word of this article explains why. It only says that food prices will remain high, and probably go up more when the tariffs are enacted, and we should just suck it up and deal with it because there’s “nothing anyone can do.”
Which is obviously bullshit.
The reason food prices remain high is simple corporate profitmongering, and the (US) government absolutely could do something about it but they won’t. Food is a product – the product – with a notoriously inelastic demand, so retailers and middlemen in every step of the supply chain can and do pad their profits by as much as the market will bear plus a little more on top. Because they know they can get away with it and the vast majority of people will have no choice but to pay whatever it is, or starve.
The margin on prepared packaged food items is typically in the order of 15-35% per link in the supply chain (supplier -> manufacturer -> distributor -> retailer). Everybody wants too big of a slice of the pie. The government absolutely could step in and pass a law stipulating thou shalt not charge more than 10% (or whatever) over your invoice, under pain of us confiscating every penny above that mark via taxes and using them to pay for soup kitchens. But That Would Be Socialism^tm^, so it’ll never happen here.
(And yes, the margins on unprocessed foods like produce and meat are slightly lower.)

- Comment on Fossil Fuel Interests Ramp Up Their “Solar Makes Electricity More Expensive” Falsehood 2 weeks ago:
Nuclear has its place in the world, and it’s pretty much a given that in order to maintain high availability and energy stability we will not be able to rely solely on one single source. It can’t be all renewables, but it can’t be all nuclear, either. We are going to need a mix of both.
Nuclear can serve e.g. big time industrial, manufacturing, or other mission critical needs with large amounts of power that is reasonably clean and, importantly, very stable.
We just need to keep it from falling totally into the hands of morons who want to waste it all on “AI” datacenters, or whatever the fuck else.

Yeah, idiots can also spill a couple of million barrels of oil into the Gulf of Mexico. Whoopsie doodle! I guess that’s just the cost of doing business, amirite? Good thing stuff like that always happens far away…

“But if you don’t pay into the grid, there will be no money for maintenance of the grid!!!”
-
What, like all these private power companies have been doing a good job of maintaining that grid infrastructure anyway? Don’t make me laugh any harder. They’ve taken all of their profits from the last century, give or take, and largely done the corporate equivalent of blowing it all on hookers and cocaine rather than reinvesting any but the bare minimum back into their own infrastructure.
-
If it isn’t profitable to run the grid, that’s great! To use an example, the sewer system in my county is run directly by… the county. It is not a for profit enterprise, because as soon as you pull your head out of your own ass you can realize that trying to make modern basic necessities like power, water, and sewer access private businesses is a moronic idea. One which leads to inevitable catastrophe, because capitalists are going to do what capitalists do. The fact that these idiots are straight-facedly behaving as if we “owe” them profits in perpetuity and expect us to swallow it is almost as bad as the fact that, by and large, the public still does.

- Comment on Septic clean out cap 2 weeks ago:
No, it’s because the county decided that “all installation and removals of HVAC, air handling, heating, and cooling equipment” require a permit and did not stop to think initially that this is worded in such an overbroad manner that it also technically encompasses window and portable air conditioners, and theoretically also portable space heaters as well. All means all. It’s just that window AC is the only thing visible from the outside of your home, so the inspectors can bust your balls for it from the street if they feel like hassling you for something.
I’m sure the local government loves it as well because if a “violation” is noticed from the street it gives them a legal avenue to enter the properties of people they don’t like (i.e. poor people, blacks, hispanics, etc.) to troll for additional citations or other generalized harassment.
- Comment on What is the limiting factor than prevents software discovery of undocumented hardware registers and instructions? 2 weeks ago:
This is an extremely high level answer, but you have to be equipped to even notice whatever it was did when you twiddled it. It might not be obvious, and this is muddied by the fact that most of the reserved or undocumented bits/registers/addresses/pins will probably do nothing. Or crash the machine. So that entails having a vague idea of what the device might be calale in the first place so you can have the right equipment or software hooked up to it to even observe results. There’s probably no automated programmatic way to do that in most cases.
It’s bad enough when all you have in front of you is a microcontroller that can only manipulate its own memory and a small easily defined set of outputs. It gets hairy fast when you have multiple special purpose chips in a system that could do anything.
- Comment on Septic clean out cap 2 weeks ago:
Plugging a device into an outlet (be it a refrigerator, phone charger, or even an EV charge cord) does not require a permit.
Want to bet? In my county, it is technically a requirement to pull a permit and get permission from the county government to be install a window air conditioner. You know, the kind you slam the window shut on and plug into an outlet as the sum total of its “installation?”
Never underestimate the insanity of the petty egos who have small amounts of authority.

That’s because there is a strong tradition of rights distribution for movies and TV being totally fucked up, and it has been since day 1 of both industries. Brought to you by the same motherfuckers who gave you Hollywood Accounting^tm^, where a movie that cost $100 million to make and raked in $500 million at the box office somehow “didn’t turn a profit” and magically they don’t have to pay royalties to any of their writers or actors.

- Comment on TPU wall thickness for shoes 1 month ago:
If your coworker’s TPU print “delaminated” easily, either by pulling apart at the layer lines or via the individual print lines tearing within a layer, he was either printing it too cold or too fast, or both. Which is a common mistake. People see the print temperatures listed on the side of the spool that are similar to PLA and assume it can just be printed like PLA. This is not the case if you want acceptable results.
You have to print TPU slowly, and if you want the strongest possible part and don’t have any tricky overhangs to deal with, you also want to print it towards the upper end of its temperature range. People will be tempted to lower the temperature as far as possible before the stuff just flat out stops coming out of the nozzle in a vain attempt to combat stringing, but this is a fool’s errand. You can never get TPU to stop stringing, so don’t even bother to try. Just clean up your finished part with a lighter after it’s done.
TPU is one of the very few materials – arguably the only such material – capable of being printed by a consumer level printer that, when printed correctly, is functionally isotropic. That is, its strength and properties are the same in all directions. Both along and against the layer lines. TPU that’s been printed right sticks to itself extremely well.
You have already correctly guessed that this property makes removing supports from it kind of tricky. I’ve never been able to achieve supports with TPU that can cleanly tear off like with PLA and other more rigid materials. You’re going to have to resign yourself to cutting or shaving them off, at least in some capacity. For the ones inside your shoe, this may present some difficulty.
The others are correct about drying the filament, also. Get a filament dryer that can feed directly into your printer. Even a dinky one will do; you don’t need high or precise temperatures for TPU drying. I have the $30 OG Sunlu one and it works fine for me.

All of human societal structure has ultimately boiled down to might makes right.
All of it.
In our modern civilization we have inserted enough extra steps in between to delude most people into believing that this is no longer the case. But still it is. I have said this nearly verbatim on here before:
Who are the cops? Just guys with guns.
Who are judges? Just guys with access to cops.
Who are politicians? Just guys with access to cops and judges.
Who are the megacorporations? Just guys with access to politicians.
Etc.
- Comment on Any recommendations for a low-cost, low-hassle printer? 1 month ago:
The first gen 3 series machines definitely had some teething troubles, so waiting on the 4 is probably a wise plan.
Me, I’m mostly interested to see if they backport compatibility for their “Qidi Box” filament changer thingy (which thus far is vaporware in the first place) to also work with the Plus/Max 3. I don’t care about multicolor printing that much so I’m not about to buy a new printer just for it, but if I can slap on an add-on I just might.
- Comment on Any recommendations for a low-cost, low-hassle printer? 1 month ago:
Even if these are overblown, I personally refuse to tolerate setting the precedent that this kind of thing is ever okay, and once a company tries it they’re burned forever as far as I’m concerned. No one needs to be spying on me, for any reason, ever, and I will never do business with anyone who did it even if it was in the past.
Bambu Studio’s extremely fishy behavior has been very well documented, and I don’t think it’s work the risk doing business with its company for any reason when so many viable alternatives exist.
- Comment on Any recommendations for a low-cost, low-hassle printer? 1 month ago:
Qidi does not have a proprietary slicer that phones home, and they have not been demonstrated to engage in any suspicious behavior.
My issue with Bambu isn’t that they’re Chinese. My issue is how they conduct themselves.
- Comment on Any recommendations for a low-cost, low-hassle printer? 1 month ago:
They’re slimy. Their machines use proprietary software and parts, and their software has a highly questionable always-online requirement that phones home back to their servers, which is something that really ought not to be happening with anything that may be able to identify what objects people are 3D printing. Even if they’ve walked back the always-online thing and allowed local only operation on some of their printers, that still demonstrates that they are not to be trusted.
Their company was founded by former DJI employees. That should really say it all.
- Comment on Any recommendations for a low-cost, low-hassle printer? 1 month ago:
Qidi X-Plus 3. If it’s anything like my Max 3, which is the bigger version, it ought to be plug in and use (after running the included calibration). It’s on “sale” right now for $500, but it’s always on sale. It’s also not made by Bambu, and if I were you or anyone else I would not give one rusty penny to Bambu for anything.
The draw with this thing is it comes with a fully enclosed chamber with a heater and PID to control it, and it’s the easiest time I’ve ever had printing ABS and PETG if that’s what you want to do. You can slap a 0.2mm nozzle on it easily enough if you want to print tiny stuff.
If you don’t care about high temperature materials you can get the X-Smart 3 which is based on the same system but is smaller and minus the heater, and is even cheaper.
- Comment on Help me identify a filament's material 1 month ago:
Well, if we’re ruling out PET and PETG – PET would probably require the temperatures you describe and would be impervious to acetone, as well as extremely flexible – there is an outside possibility it could be HDPE.
HDPE filament is damn rare, though, and I’d doubt anyone would be giving it away as samples given how difficult it’d be to print with most consumer machines. HDPE’s signature tell is that it feels somewhat waxy if you e.g. scrape at it with your fingernail.
- Comment on My personal benchy: this one really tests a printer's capabilities 1 month ago:
The other point here is that if the lenses a user gets don’t quite match the frame you could always just tweak and reprint the frame a bit to match the lenses. That’s not really the end of the world, but I don’t count on any opticians to understand that. The concept of a user being able to so easily self manufacture a set of frames is probably completely alien to them.

- Comment on Glow In The Duck 2 months ago:
I’m using a diamond tipped nozzle, 0.4mm. I understand that smaller nozzles like 0.2 don’t play well with filaments filled with solid materials, and the glow stuff suspended in this is indeed a solid material.
Temperature may be an issue, but I wouldn’t know. I print PLA typically at 230° C, including this filament, which I am certain many people will find jowl-flabberingly appalling but that’s what I do. My machine goes pretty fast and I found that gives me the best results.
