This is a lens holder for the Durovis Dive that uses larger lenses. The lenses are easier to adjust than the stock ones, and provide a much better overall field of view.
This is currently arranged for my 56mm IPD, but can be adjusted for others in Solidworks. If you would like an STL of other sizes please let me know.
This uses the same lenses as the FOV2GO. I got them from some magnifiers sourced at Fry's Electronics, but they can also be found on Amazon.
This magnifier is the UltraOptix SV-2LPLED 7X Aspheric LED Lighted Magnifier.
This mod is a major improvement over the stock Dive lenses, and I highly suggest you try it. With this simple modification, the Durovis Dive is a truly great mobile phone VR headset.
