I had my now-wife's engagement ring custom made when I was planning to propose years ago. I had it made in 18k white gold but we've found the constant need to "dip it" to be very frustrating and annoying. So we were going to have it remade in platinum and after feeling I got burned the first time around and seeing shapeways started 3d printing platinum, I decided to try my hand at creating the 3d model. But I found the learning process took a bit longer than I liked so I came here to have it recreated. I had a great experience but after having test pieces printed in Frosted Ultra Detail Plastic, my wife has informed me that they are thicker than she'd prefer. I have .3dm and .stl files of 2.8mm thick engagement rings and wedding bands, but we'd like them much thinner AND with the stone's setting as low profile as possible. The previous designer, that did a great job, didn't think it was possible with the current design so I'm coming back here for ideas.
