Allow at least two objects in one file for "stainless steel" and "silver".
Right now you can put two objects in one file if it is an earring or cufflink. All other multiple objects will be rejected. E.g. a locket, made of two parts, won't be printed.
It should be possible two put at least two objects in one file, no matter what it is.

The rule for stainless steel was changed recently but it's still not clear definde ...
It doesn't really matter what policy Shapeways institutes, but let's have a consistent and clearly stated rule. "Earrings and cufflinks only" plainly is not that rule, since objects that don't obey it are being printed.
My model, Pendant Cage. is two pieces and I have not had the model rejected. How would my pendant count as OK under the "earrings and cufflinks" clause but Michael Mueller's Floral Locket wouldn't? Either both of our models should be printable or neither of them should be.
Earrings and cufflinks are allowed to be printed in pairs because it is traditional, but the processing resources for a pair of earrings or cufflinks would seem to be identical to the processing resources necessary for any two objects of similar size. It should not matter what the purpose of the end product is, the policy should be based on the number of objects in a file.
I propose that Shapeways institute a policy based on the number of objects in a file. Two objects in a file would not increase the handling cost, and each additional object after the second should be a set fee ($3-$4) per additional object.
