This is based on the ring shown in the Dark Matter series for the character known as Four (or Ryo Tetsuda). This design is not 100%, I could not get the band shape exactly right, but I may try a redesign if I have time.
I did ask permission from SYFY (http://www.thingiverse.com/Syfy/about) prior to posting this.
I have included a ring size template for those who want to print the right size the first time and I will include ring size variations from size 5-13. The original ring is larger than a 13 and the V2 is just under a size 12.
1) Print it.
2) Paint it.
3) Wear it.
