Looks nice, but there's no license. Can't do a thing with this.

You can do this by doing as little as making a single file named LICENSE in the top level directory, with a single line:
This work is licensed under CC BY-SA 4.0. To view a copy of this license, visit https://creativecommons.org/licenses/by-sa/4.0
That's it.It is the hardware/artwork spritual equivalent of GPL2. It means the user must not remove your name, must make source/plans available, and commercial activity is ok.
Just a suggestion if you don't know where to begin or what to do, hadn't really thought about it or read up on all the infinite options etc.
