15mm Scale Drone Piranha

I remixed the excellent design by [Cogboy](http://www.thingiverse.com/Cogboy/about) to fit 15mm scale for games like Gruntz or any other 15mm scifi game.

Also included an alternate drone armament of twin linked chainguns that weren't in the original model. I used some geometry by [Ologhzul](http://www.thingiverse.com/Ologhzul/about) to help create the chain gun model.
