Your 3D model is the only stl model of ring of the lucii in the whole internet. I printed mine in XYZprinting da Vinci Mini W which is not on the list (link here: http://us.xyzprinting.com/us_en/Product/da-Vinci-Mini). I used black PLA filament. I was trying to soften raw 3d printing with acetone and wipe edges with fine grain sandpaper to gain a shape as similar as original ring of the lucii. As primer I used gesso and then I glued flakes of aluminium to inner side. I couldn't find those rose gold metal so I used aluminium which was less expensive and I think it matches better to white swarovski crystal. For protection I used varnish so it gives a shiny surface. EDIT: Original size of printed ring didn't fit my finger so I had to cut out a piece and glue together.
