Ring Presentation Pedestal

I designed a little pedestal to present a pair of rings such as wedding rings. We are using this for the wedding to present the rings in a little glass box with some dried flowers.

As designed, the rings are 21.4 mm and 21.7 mm in diameter, 3.0 mm and 3.5 mm thick, slightly shifted to each other and about 15° inclined. The pedestal is about 14 mm high. I could, however, adjust the parameters to other sizes if necessary.
