the pawn.
i think for the big scene is wise to make the individual blender.file but for the simple scenes, It’s great to make in one blender.file but all of it, back to the purpose of the project again.
For the case of this pawn chess, i made a different blender.file, i made a copy of the base and save it as a pawn.blender in case I want some change to pawn design I can just make the change of the single blender file.
