Most certainly, I have not read T5, nor the novel, so I honestly don't know how Maker technology is portrayed.
As it is, I project what my little Pooh brain can based on what we've seen so far in what is popularly called "3D printing".
Despite A. C. Clarke admonishment, I think it's a laudable goal, even given it's "high technology" to try and keep things from being "magic".
And Maker Tech I think can easily be extrapolated to something akin to magic. Diamond Age kind of stuff.
Historically, we've kept Traveller to a sort of Firefly, "1980's with Fusion power" kind of world.
The trans-humanist aspects are one thing, but simply dealing with a post-scarcity economy and society are another.
Already we're having difficulty imaging a world where many mundane tasks are automated, as automation continues to advance.
But we've had automation on a large scale for some time, due to the costs and complexities of automation. There are machines that can make a pumpkin pie. Well, I should say there are machines that can make 1000's of pumpkin pies, but not a single pie. It also can't easily turn around and make an apple pie. I can do that, I can make both an apple pie and a pumpkin pie in a couple hours.
However, with the machine, it seems the limit of human interaction is dumping bags of flour (large bags) along with other ingredients in to hoppers. The interactions with my pies are a bit more intimate.
As for Makers, right now we can "print" solid metal objects (there's a famous example of someone printing a .45 pistol, I don't see to recall if they printed the barrel or not -- but I think even that is possible). But the characteristics of "printed" metal is quite different from machined metal, or cast metal, or forged metal.
But what if there is a localized, very intense gravitic field within the Maker? Perhaps that can be used to simulate forging.
Today, you could 3D print linked chains, which is pretty neat when you think about it. The idea of printing a linked items, a ball in a box, or a Ship in a Bottle. But our current material limitations wouldn't let us put any real load on that chain I don't think.
Also, we're discussing the limitations of not just manufacture, but assembly, etc. But I think if we're able to create Makers, having autonomous machines able to cope spatially and having appropriate manipulators or bits, sockets, or drivers, should be able to assembly anything they're told to. Now your ship engineers are there to second guess the machines, there to add context to the fabrication task that the machine may not be able to grasp.
Note, I'm not using any terms like AI here. As we've learned so far, anything we've called "AI" in the past is really not much more than an interesting, task specific, sorting algorithm. The problems now is that we have general learning algorithms that we train. We don't tell the software how to, say, identify a table lamp. Rather we show them thousands of "things that might be lamps" and give it treats when it guesses correctly.
But to that end, after the training, we can't look at the data and say "Ah, yes, see here? Lamp". We're in the age of "not knowing how it works".
So, despite every reason for the future to be some kind of low scarcity, heavily automated society (at least as it evolves, if not by choice), Traveller is still "shotguns in space".
We like our technology to bring convenience to our lives, but not to make us redundant, or worse.
"Why am I paying someone for +4 Broker when there's a app for that?"
Or, "Yea, this is another AAA Scenario. An automated Scout ship was sent to a system, where it was projected to deploy 50 drones in order to perform a 6 month mapping and data gathering mission of the 4th planet before returning. It's latest update is overdue, and our automated recall ship has not returned either. So, neither seems to not be responding, so we need you to go out there and tow then back home."
"Recall ship?" "Yes, we send those out to essentially Ctrl-Alt-Delete the Scout ship and tell it to come home."
