I've also adjusted the default thread tolerances to print loose on my CR-6 SE, but if you have a newer/better printer, you can probably reduce the thread tolerances.
If your printer has any stringing whatsoever, I highly recommend printing each piece separately. If you print the bolt + cap + nuts in one go, the nuts may be far tighter than if you printed everything separately due to imperfections left behind when the tip moves from one part to another.
