About this 3D model

I fell in love with hotkey's Ninja Fridge Shuriken http://www.thingiverse.com/thing:6383and so designed a few of my own, and based some on http://www.thingiverse.com/thing:323I put holes in the middle to cut down on plastic a little. and beveled edges but tried to keep it to 60 degrees so you shouldnt have a problem printing them.
