Need help figuring out how to make this model.

Alright guys, I’ve got to figure out how to make this bead model. At first it looks simple but when actually executing it, It started to get confusing. It needs to have the exact cuts and twist the same way. I’ was able to get the twist but the angle of the facets eludes me. Any advice would me helpful.
this is the diagram for the bead.
This is what it should look like

Yes! how did you do that?

Well, I used boolean operations with an array modifier to get that shape. I’m willing to share my file with you if you want it? The file that has everything before it’s applied.
