Rings: Harmony of Contrast

I like plain but stylish rings. I'm not a big fan of ring with head. Instead, I like to play with colors. I choose to play with the contrast of colors (i.e. black and white) to make my rings look classy. The patterns are simply: alternating black and white strips. However, you can choose your own favorite colors.

I design two rings. One is a thinner ring with uniform strips, and another is a thicker ring with non-uniform strips. 

Below, you will find STL files for both patterns. Each file is a half of a ring. Print the same file twice to create one ring: a half with white material and another half with black material. I can now combine the two halves together to harmonize the contrast of the colors into one.
