This Shuriken is based off of Hatake Kakashi's Kamui Shuriken, specifically the ones shown in the Naruto: Ultimate Ninja Storm 4 game.
The whole shuriken is printable via the ShurikenWhole.stl, but it tends to have some defect on the tips of the blades, so it is also printable by printing it in two halves.
To do this, print the ShurikenTop and ShurikenBottom as well as 6 of the Stabilizerx6. Then glue the stabilizers into one of the halves' holes, then glue the other half on accordingly.
