Back from my vacation, I had the joy to see that my Shapeways order came in :
A Dragon Ring in "Antique Bronze Glossy" :
I'm happy with general outcome. Some details didn't come out (the tongue), but that shouldn't be a problem for finer materials.
And a set of 10 25mm Industrial Bases in "White Strong and Flexible Polished" :
95% of the details came out perfectly, some bolts disapeared, but for gaming usage the quality/cost is fine.
