Convert it to an Editable Poly and select the circle shape polygon.
Edit the polygon following these steps: Bevel [Height=1; Outline Amount=-1], Bevel [Height=7; Outline Amount=1], Inset [Inset Amount=2], Extrude [Extrusion Height=4.5], Bevel [Height=3.5, Outline Amount=-1], Bevel [Height=0.3, Outline Amount=-0.3], Inset [Inset Amount=5.5], Bevel [Height=-0.3, Outline Amount=-0.5].
Unfreeze the first object and create a compound object out of the two, by extracting the second from of the first one. (Note: Move the second object a bit lower so the bottoms don't overlay thus creating weird compound geometry)
