Itried to model the case with a helical sweep but cant seem to get the right thickness at one end (see note 3 on pdf file). A trapezoid sheetmetal is rolled along its diagonal (i think) to form those seams curves you see on the drawing. Then cut at both ends. The grab ends are rolled and touch each other forming3 times its thickness at one end. Then tucked in. Makes sense. I have a video of it as well.
I appreciate any help.
