this is a modified version of the Dive Vr headset (http://www.durovis.com/index.html) it has spots for 2 magnets to give the same effect and function as google cardboard. These files are made to fit the note3 but will work on most large profile phones.   The Oculas rift v2 uses the note3 display so this has to be good right?  these files are now V2 I have printed a few sets and made the clips fit better and the eye pieces fit way better. I now have a working version of this on a note3   the magnets I use I found on amazon at http://amzn.to/1pz1NK6 I use 2 of these because it works best for strength through the magnets.  the eye50mm file is for a 50mm lense that I found on amazon at http://amzn.to/1pSbuCl I used these lenses for my cardboard project and they worked amazing and I had some issues with the lenses I got in a 'drive kit' .
