I don't have one to share but making it yourself isn't very hard at all.
1. find a library tutorial this one is as good as any
2. find the SC70-6 package drawing online and download it
3. draw the package footprint with the library editor
What you will quickly discover that it's actually pretty easy. The big problem with eagle parts you find online is that they are often wrong. By making your own you can be certain it is correct.
