STL Blank Library - Elos?

[BlueSky]

I am looking to download a library of STL files of connection independent blanks. I understand that Elos has such a library that is "certified" by 3shape (free for the connection independent library) but can not find the library online.

Does anyone know where such a library (Elos or otherwise )can be downloaded from?

Thanks,
Michael
