Outsourced Wearable Object

Here is my original 6 rings design.
I really want to make industrial quality design. 
I focused on making lines that were comfortable and soft to wear.

I chose these three designs and took them to the last class.

We did group critique, they said simple and soft lines were good, but the design was not unique.
To further develop the design, a twist in one ring was inserted repeatedly.
Here is my final wearable ring design.

And then, I uploaded to Shapeways. I check the small two red dots.
I guess it is not a big problem.
