Battery Snuggie for SYMA X55W Quadcopter

I noticed battery packs sliding around inside the SYMA X55W, which was causing the center-of-gravity to shift around while flying. So I made this brace to hold the battery more securely.

Note: In order to install this, you will need to take your quadcopter apart.
