Badminton Racket with Strings (and keyring option)

This is a remix of Neils4140's badminton racket, but with strings, since the STL doesn't have it. There is also a version with a ring, so it can be turned into a keyring. I modified it to print for a friend. Haven't printed it yet, so this is still a work in progress. In the meantime, please let me know if any edits are needed.
