I know the changes are subtle but I'm really looking for any feedback on improving the next version. I know one thing I'll be focusing on is blending the battery box on the bottom better with the main body. I am using a small project box from Radio Shack and the edges are slightly rounded so it stands out when placed on something flat. I'm thinking of first trying to fill that gap and make it “squared off” with something like bondo and see how that goes…
