In the comments the guy says to "Make many copies the red part and use Cavity", but I have tested that out and haven't had any success. More specifically, I've tried:
- making a cylinder and mating the outer face tangent to one of the red part's faces + adding other mates so each part is oriented properly.
- using circular pattern to add the red parts all the way around
- using cavity feature with all of the red pieces to make the yellow piece
