This is a remix of the “Combined Base” of the Magsafe Charging Stand by @Grant G. https://makerworld.com/en/models/153155. All of the iphone and apple watch holder plates are available in the OG post linked.

I added a cylinder to the rear of this base to act as a ring holder. The cylinder measures at 16mm diameter and 35mm tall. I can alter and add other sizes if needed! My ring size is 13 and there is plenty of room as seen in one of the pictures.
