Very nice pieces you've modeled there, I was just going through how we would of done this say 20 years ago, it would of been longer and even more pricey, it would of been out of reach to most hobbyist.
Here are some photos of the small stuff I have had printed by Shapeways.
All are plastic of various kinds except the yin/yang piece which is stainless steel.
The little boxes are about 3" tall ... the pendants about 2 and the bauble is about 3.5" in dia.
I am having fun with this ... experimenting so far ...
