We don't currently offer chains, and you wouldn't be able to print it in metal. You could print something like that in one of the plastic materials though, if you model it.Your friendly neighborhood Moderman
You would have to order the parts separately and do any assembly yourself, but yes you can get multiple materials. They have to be 2 separate files, and ordered in the separate materials. Your friendly neighborhood Moderman
I just create the pendant and purchase chains/closers at Michaels, then sell the pendant on Etsy. I need a higher markup though, and I don't get many sales because of it. Would be great if Shapeways could start offering chains with pendants for a premium.
