I’m currently working on a slight redesign of my small jeweler’s vise. I’m trying to extend the jaw opening, and to do that, I’m switching from a standard nut to an internally threaded pipe. However, I feel like there might be a better solution out there. Ideally, I’d like to attach the threaded component to the endcap rather than the main body. If anyone has recommendations for a better internal part or I’d really appreciate it.

-A drawing/sketch of what you want to do would help. My visualization may not be the same as yours

Above is a search for acme nut which is what you probably want. I'm assuming that the screw on that is a acme thread of some sort and you can get the nuts with a flange on them that will probably adapt it to the end cap. Unsolicited advise, get a bigger vise to do the job so you don't extend the slide to much and break it due to not enough engagement in the bore.
Do you know the collector value on that vise? Might want to know that before you molest it.

no neat sig line
To put it simply, the current design uses a 44 mm nut. I 3D print a part that allows the nut sit on as reduce the overall length in half to 22 mm. Unfortunately, this creates two issues: first, it shortens the usable length of the slide because the cavity is now partially taken up by the nut; second, it limits how far the vise can open.
I’m aiming for a design more like the Wilton Bullet (Baby version), which has a system that works similarly to what I’m trying to achieve — if you’ve ever seen one. I could probably sketch it out, but essentially, the mechanism “hovers” inside the body and is attached to the endcap, rather than running along the bottom of the body where it takes up valuable space. That extra space could otherwise allow for a longer slide and wider jaw opening

Just to be clear, this is a jeweler vise it’s size is Paramount, which is why it’s useful for specific uses if I can allow it to open 40 mm instead of 22 it makes it more useful and obviously if someone stupid enough to put something on that is too heavy or too overpowered. That is just a lack of common sense but a large brooch or something to that effect might require

Look at Fireball tools vise as what you are describing is his nut design. Abom79 on youtube built a complete USA cast Fireball vise, he has a video on modifying the nut to accommodate his new lead screw it may be just what you are after.

This is a good idea. It would allow you to simply use a bolt through a washer at the rear end and then just use a nut at the back end of the dynamic jaw inner tube.
It would probably require a redesign of the dynamic jaw to create a "tube within a tube" where the the outer tube doesn't rotate and the inner tube does. That might be tricky while keeping the design of the wilton vise.

I don't see it. The outer "tube"--the slide--is already keyed into the static body.
