Ninja Shuriken sharper

I saw so many people enjoying the first version I thought I would also share this second version I created which has sharper knife edges on each tip as well as a sharpened point on the back side of the support arm.  (as you can see in the photos of the back).  These enhancements don't affect printing or bed adhesion, and only slightly decrease tip strength, while improving its piercing ability.  It also made the print time slightly shorter and reduced the amount of material used.

Besides all that, I think it looks even cooler!
