Here is a simple coring as a material saver: You could even make the wall at the screw define a centering locator and loosen the rotational lock's diametical fit.
Ribs would be optional at this step.
Of course, making this particular core really hosed the Rounds.

Just curious why you add the step back into the slot versus remove the material? Any adherent benefits of adding material versus taking away?
Absolutely... I am not bound by tooling and machining processes. In this case, I am simplifying the wall feature (slot) cut. When I can create a draft face with a single cut, rather than a "merging" features, I will.
I see now how that simplifies things. Before I saw you post about the material saver, I was extruding into the surface from the top versus doing a revolve. I like the revolved better.
Since the hole requires draft anyway, I have no aversion to making it a simple revolve. The same with the slide hole draft. I did form the thread using the hole feature so I could inherit the drill diameter from the tables.
I come from the 2000i world where all holes were essentially a revolve feature.
