Here is a Wedding Ring That I designed for my partner this ring is a Full Band twisted Ring Court Profile with Four evenly spaced Sizing breaks one in each corner, with a bypass and a half Carat circle cut cubic zirconia or 0.4 Diamond held in place by a 4 prone setting. This Ring I tested printed in Silver PLA and Transparent Blue Pla, I've also included a few different variants of the ring Without the sizing breaks the rings are currently sized at a 6.5 US or there abouts, you should be able to scale the ring in your slicer to better fit your finger. Also comes pre-painted in 3mf, Print settings, Nozzle size 0.4mm, Layer height 0.2mm, I tried at 0.1mm but it didn't make much difference, Print speed 100mms Or less, Infill 15%, Wall count 3, Supports needed, Support type normal,
