Alright (cool design BTW), first I made a spline of roughly what I wanted (you can insert your image to trace it) for a pair of those shapes, optionally using two concentric arcs/circles for guidance. Note that while drawing the spline holding Ctrl down will prevent snapping and other auto stuff from happening. Once done with a rough spline, I click off of it so the tangent bars all go away, then easier to drag the spline points around to do fine adjustment.
I then did a circular pattern of that pair to make six of them.
I then selected the original pair (using click drag selection from left to right so circles not selected too), and did a Move such that all 6 came together, so there just a small gap between edges of all.
I then added a Coincident constraint between original pair and neighboring pair, and moved resulting point around a little to get good curvature of now joined line. Nicely the rest joined automatically also so now get shaded tan profile that we can extrude!
Here is the cool profile extruded, and I have next defined a sketch on the top of the extrude, in which I drew a larger concentric circle, and used resulting outer profile to extrude downwards to make the lip.
Finally I did a Modify > Fillet to the upper and lower edge of the lip, and viola!
Hope that helps.

I was just thinking now it would be helpful to make two lines like this from the origin, and add an angle dimension by choosing the dimensioning tool, then one line, and then the other and enter 60 degrees for the angle, so can then draw the spline pair to already be in correct position. That's part of the fun of this stuff, many ways to do it!
