Parametric Chamber Flag

I had some orange plastic in the printer after Halloween that I wanted to use up so I figured I'd print some chamber flags. I didn't want the heart one on here and although I like the 22LR one here I wanted something in 556 so I coded this up. I started with a 5.56 NATO round I found here (http://www.thingiverse.com/thing:55798) and then replaced it with a SCAD generated round rather than the STL import. I left the import in as a comment. I included some modules to make 5.56 NATO, 7.62x39, .
