Pinshape is a new marketplace for 3D designs. According to the website you can not only upload and sell your designs but you can also get it fabricated on demand and shipped to you.
Open source electronic projects
Thanks for the mention! We’re kind of like a next gen marketplace that mashes up the professional print service like Shapeways, the ability to download for your own printer and a curated designer community full of files that have all been verified printable. We hope you’ll check us out!
