I am not sure which of my settings contributes to this discrepancy. I noticed this on another model, which has a more dramatic discrepancy. But it's a paid model and it takes ~10 minutes and 30 GB of ram to slice, so to save you time and so as to not run into licensing issues, I replicated the error with the primitive shapes in the attached 3mf file.
