I design baffle bores to open up in steps towards the front.  So, getting the least blow-by at the start, with lower risk of clipping near the front end.  Something easily done in single insert design rather than multiple stackable baffles.   Then you would need to keep track of which goes where.  Possible, but a nuisance.

You could add features that force the order of the individual baffles in a stack, but that seems like a lot of work, when combining them into longer sections seems so easy.

That's a good idea.  Next one I design will have a slight outward taper in the bore.  That and a slightly larger adapter face to seat against.  In the end, though, one is fighting gravity and relying on the stiffness of the material to prevent sagging and clipping.

Still don't know how to force constraints on the slicer, so that key constraints are met.  Seems like the process is print, fiddle, print, fiddle, ... With long prints that seems inefficient.

Key constraints as in key dimensions, or something else?  Are you using Cura?  Either way I can offer specific or generic suggestions if you're interested.  Sometimes it is try, fail, modify, repeat...sometimes the first educated guess actually works!

Key dimensions.  I'm using Prusaslicer.  I've been burned before on this try, fail, modify cycle a few (more than a few) times.  I don't mind on a 20 minute print, but on significantly longer print times, it's a pain.  Sometimes the bore is critical, sometimes the exterior, sometimes both.  I do realize it is a 3d printer and I'm dealing with plastic, but, you'd think there would be some knobs to control in the slicer.  There probably are - but I don't know what they are called.

Must have got lucky, my LDC came out ok.  I did run a 0.2500" reamer down it.  Did some test firing on a 1377 and 1322 and no disaster happened.  Haven't tried it on the 2240 yet, but I'm hoping my luck continues...

big prints.... can be broken down into smaller "bites" that dont take as long

depending on where the bits in question are, you can do some of that in your slicer
