Generic for our days mock to Carrera y Carrera's Mi Princessa rings. But adapted for poor people: here is no ornament like an original, another thickness (1.65mm) and lots of differences in many nuances. So my version of crown shaped rings is far from original but very cute (and made with high quality).
Set contains STL model ready for printing and Rhino3d 3DM source file. This rings was successfully printed and produced in metal. As you can see on some previews, STL's are flawless.
Sizes from 16 to 20.
Model volume varies from 352 to 432mm^3.
Estimated weights:
Gems: diameter 1.1 and 1.5mm diamond cut
OBJ is not tested (anyway OBJ format is useless for production when native model was made in Rhino), exported from Rhino. I added OBJ's just for better publishing and placement after stupid recomendations of CGtrader (probably for smart heads from CGt quantity of junk and thumbs is more important than quality of models).
