Corner for 2020 Extrusions. Holes are not centered on purpose, they are moved out towards the edge in order to provide more clearance for the bolt heads. It's already close on aluminum ones, but these are a bit thicker to make up for the difference in strength of material and that thickness would have compromised the already small clearance. Outside faces were left flat for printability.
