All 10 of the Akatsuki rings from the Naruto anime. This one was a bit difficult due to the inconsistency of how the rings are portrayed in the anime, and finding kanji that matched was pretty tricky. Each ring should have a default horizontal inner diameter of about 1.9 cm., with the vertical slightly shortened by the top mantle. Below is a list of each of the rings' respective owners, the ring position, the background color of the ring, and the meaning of the kanji.
Pain: Right thumb, light purple, Rei-zero
Deidera: Right index finger, teal, Ao-blue
Konan: Right middle finger, white, Bya-white
Itachi: Right ring finger, red, Shu-vermillion or scarlet
Zetsu: Right pinky, green, Gai-"boar"
Orochimaru: Left pinky, dark blue, Ku-"sky" or "void"
Kisame: Left ring finger, yellow, Nan-South
Kakuzu: Left middle finger, dark green, Hoku-North
Hidan: Left index finger, orange, San-three
Sasori/Tobi: Left thumb, purple, Gyoku-"jewel" or "ball"

Print with a raft and supports. A .3 or below layer height should be good. As with just about any ring, a 50% or above infill should be used. A may also be a good idea to print it 90 degrees from the x-axis to counteract stress from wearing it. Take care when removing the supports. Enjoy!
