Safer Baterang

I remixed iwinn74's great Baterang model to be a little more kid friendly. I needed Baterang's for the utility belt of my son's Batman Halloween costume. But the current design was very pointy and quite sharp. All I could hear in my head was "You'll put an eye out!". So I decided to round off some of the sharp corners to avoid a trip to the ER, should my son throw one at a friend's head.
