Inspired by the iconic ninja weapon, this 3D-printed kunai has been reimagined as a functional fidget toy, combining aesthetic appeal with hands-on interactivity. Engineered for durability after extended testing, the main body is printed solid for strength, while the spinner insert offers a precise press-fit connection, requiring no glue or hardware. The value of the diameter is in mm. The spinner insert is parametric, and you can specify the diameter so you can adjust it to fit your finger. You can always reference the provided print profiles for recommended settings. Please note that the end is pointed and can cause damage if used carelessly, so please be careful.
