I am trying to model the attached file but I keep getting stuck. If anyone could help me out either with a list of steps or doing a solidworks model. It would be greatly appreciated. I really want to know how to do it, so if you decide to make a solidworks part, it would be preferably left in part format.

I have only attached one half of the barrel cam because for the other half, it is the same part but just flipped and rotated.
