Here are two interesting sites I found recently.
Sculpteo 3D printing site where you can not only upload your design for printing, but also open your own online store in the 3D printing marketplace on Sculpteo.
&
Materialicious™ (“shelter, materials and objects”) is a user-submitted visual curation site featuring modern architecture and design, art, craftsmanship, materials and products.
Submit your art or your 3D Design items for feature articles.
