Here is a drawing depicting the layout of thick and thin sided cases, like my 585/375/416 HE thin sided ones and the thick one in picture. And my 585 case is not perfect, as where it transitions from the heavier corner to the side it isn't gradual, so case separates there shortening case life. There...
