One half of a Genji Shuriken from Overwatch. He's my favorite and I hope to cosplay him soon. This is the first part of the project. You'll need to print two of them out and glue them together to make a whole one. Do not aim at eyes or face. Don't throw at people or animals. Only throw them at Mei. I don't like her.
Edity Edit: Added the v2 file, slightly more accurate. Also added images of painted copies that I modeled and casted from the printed master.
I used 123d Design and Inkscape for this, it's a pretty simple model. First I made an .svg path of one half of the point based on the character reference material. Then I modeled and mirrored that point in 123d Design, and used a circular pattern for the other two points.
