This works well only if your manufacturing process produces an isotropic material. SLA sort of does; it's equally strong in all directions, but there is a layering axis. Filament-welding printers don't have that property. The material is much weaker in the layering axis, because the welding between layers isn't very good. Things have improved somewhat, but strength of things made from ABS filament is much lower than the same part made by injection-molding ABS.

Isn't that offset in this case because those connectors have elements protruding at many angles? You'd be weakening some and strengthening others, unless they were designed with a particular print orientation in mind.
