Design the mating surface such that there is a physical hold in the worst load directions. I've seen dovetails used fairly often for this. Then use adhesives or mechanical fasteners to limit motion in the other directions. You could also design in glue wells for an epoxy bond.
I'll try this. But this might sometimes result in more parts. Example: Z height of the printer is 200mm, part height is 400mm. Splitting results in two 200mm parts. Using dove tails would result in 3 parts because of the dove tail length. They might be even harder to align in case of kinda thin walls (1.8 - 2.4mm).
If you want to get a rough approximation of the ability for an adhesive to hold, look at the stresses in the contacts. If they exceed your adhesive bond or material strength them you have a good idea that failure will occur at the bond line (assuming its not in compression).
Unless I'm using customer great materials and those mostly provide only information about the final strength (Endfestigkeit ) like 1300 N/cm². Sure, I can gather the surface size from Fusion 360 and can compare it with the test results. But would be nice to add this as a parameter. Like a limit or so.

Hmmm - how would you do this?
Analyzing adhesives can be much more complex than many people realize.
I can imagine this.
