The designer I was working with did a decent job but had limited experience with output. Thus he delivered a ring that did not meet the specs of a Shapeways print out. This is particularly notable in the #'s that circle the ring’s head. I did have a print made and most of it looks fine – details on the side of the ring that were too fine were simply dropped.
Bottom line, I’m looking for a designer with experience with print specs to polish this ring for print. Blender file is too large to attach. Here is a link: https://drive.google.com/file/d/0B_cgZdxZbPZ8Y3VPeEtMV0N4T28/edit?usp=sharing
