Originating in feudal Japan, the senban shuriken was a staple tool for ninja, favored for its portability and tactical utility in espionage and close-range combat.
The design varies from school to school.
To my knowledge, this square-like form is used in Togakure Ryu.
My design is a training version of this traditional weapon. I recommend printing it with flexible filament like TPU with a 50% infill (the heavier the better).
