Make two separate parts in CAD. You can join them as separate shapes in a Parts Workbench compound or using the Mesh Workbench tools. Then upload the meshed file into the slicer. Empirically tune the gaps to suit your printer.

The letters are separate parts - well, bodies:

Basically I use the same shapestring to cut the letters into the shell and pad each letter as a separate body.

I thought about somehow pushing the lateral walls of the letter recesses in the shell outward to create a gap around the letter bodies, but I haven't figured out how to do that smartly in FreeCad. I have a feeling I should work on them as meshes, but I've never used the mesh workbench. Is this what you're suggesting?

Of course, I could also import the body in Blender and do that there.

Personally, I like to use manual inserts or layer changes. Print your text separately in one color. Recess the text in negative for a few layers. Then add a print pause where you drop the lettering into the designed voids and continue the print, letting the voids and bridging bond the inserted letters.

Wow I'll have to re-read that when I'm fully awake: you totally lost me there 🙂

If you design the 0,0 location of the parts so that they import into PS already aligned but as separate meshes, you can also use the elephants foot or other unique settings to manipulate how each section prints.

They do import as separate bodies that are aligned. I did try messing around with settings in individual parts, but it didn't do anything.

You're correct. A 0.2mm nozzle would certainly improve things. But it would also make printing those tabs unbearably long.

I wish my company had bought a 5-head Prusa XL: then I could have loaded black PLA and white PLA in two heads with 0.2mm nozzles, and a separate feed of black PLA in a third head with a 0.4mm nozzle for the rest of the parts that don't need to look nice. But... ours only has two heads and it's 0.4mm on both, because all the other parts we prints just don't need finer details.

I did. No difference whatsoever.

So the guy printed throwaway first layer that he filed off to uncover nice- (or at least nicer-)printed letters underneath? Interesting concept. Too much time to spend on my little tabs though, since I make them by the bedloads for our many cables, but I like the idea.

Thanks!

Yes, they're perfectly serviceable. I'd just like them to look more "professional" I guess, for my personal pride 🙂

So why not put the letters in the flat piece? That way you can print them either way up.

Good thinking!

In fact, that's what I did first: the markings were on the lids rather than on the shells.

The problem is, because the lids are dovetailed, they're narrower than the shells they dovetail into, so the width for the markings is reduced. meaning the letters need to be smaller, meaning they look even worse on the lids.

Hmmm... This setting looks like it could be the soruce of the issue:

Can you change it only for the 1st layer? Because it's correct for the rest of the part.

Good tip. I shouldn't have too much problem with adhesion with the XL, since it's a coreXY printer. But then, I left 256 parts printing at work on Friday, and this is what the printer cam shows today (I'm at home at the moment):

So yeah, even printers that don't shake the bed can have adhesion issues.

I'll try that, thanks!

How do you change the color sequence? I couldn't find anything in the settings.

small text is notoriously difficult to print

Actually, when printed topside, even 3mm letters are quite decent. They're only one line thick, but they come out quite nicely considering. They're not flawless by any stretch of the imagination, but they're perfectly legible.

When printed face down however, they completely disappear into the black. I had to increase the size to 3.5mm - the maximum before the markings run off the models - to make them legible at all.

I tried with 0.2 mm elephant foot compensation, as well as no compensation. It doesn't do anything.

Also, whatever compensation should happen with both heads. This problem is one color bleeding into the other.

It*s tough for us adults to be governed by immature bratty kids and not being able to give them the good spanking they deserve and move on to things that really matter.

Derek Sanders, the elected sheriff of Thurston County,

For a minute, I thought they had raided Harlan Crow's residence. But his Nazi memorabilia collection is in Texas, not Washington state. Also, he's a well-connected billionnaire, so he's unlikely to be raided by anyone.

I fail to see Discord as anything other than IRC with too many emojis and primary colors for the short of attention span, implemented as a humongous pile of Web 2.0 nonsense, with Big Data surveillance built in.

Privacy and resource comsumption issues notwithstanding, the few times I've had to use it to connect with people in certain communities that could basically only be found on Discord, it was unbearable to this gen-Xer: it's just as fast and as shallow as IRC, but somehow I feel the extra symbolic and color overload would have triggered a seizure if I was epileptic. It's maddering.

Oh well, maybe I'm old.

I'm astonished that there's anybody left at the Central Bank to collect and process economic data after DOGE.

I mean Musk managed to fire everybody who could put hard numbers on the humanitarian disaster caused by the shuttering of USAID. You'd think the first think he'd do - after firing those who investigate his companies of course - is to fire everybody who could shed light on the Trump economic disaster.

And yet... apparently he didn't.

So the economy is going down the shitter is it? Color me surprised. The question is: do the idiot MAGA voters finally realize what they done did? I'm not even sure they do even at this point...

When you use the Discord app, you use a browser - Chromium specifically: Discord is an electro app.

In other word, if you already run a browser that burns hundreds of megabytes of RAM, disk, and requires tons of CPU do display simplistic things, as browsers do, you might as well use it to access Discord instead of running a second insanely wasteful browser disguised as a native app.

My experience with Discord, period:

I hate the Trumps as much as the next guy, but I specifically refrain from dumping on Barron Trump, and you should too: the kid hasn't yet said or done anything that indicates he's going to become a dirtbag like his father or his retarted siblings, and he might very well choose to decide to distance himself from his terrible family.

Same reason why I don't dump on the Musk kids: at least one of them is decent, and the others might become good people too and they deserve a chance.

Give Barron Trump a chance too.
