OpenDive is a really nice looking model created by Durovis. It sliced nicely, and printed in about 8:30 on my Prusa i3. I couldn't wait for lenses from Amazon, so I found an old junk pair of binoculars, and scavenged a pretty good pair of lenses from them that fit in the goggles. Focal length is off a bit, but at least it gave me a rough idea of how these things are going to work.
Next step: download the Dive City Roller Coaster app on an iPhone and take a ride. These things are COOL! I also downloaded Protect The Planet from the windows app store and played this VR asteroids game onmy Nokia Lumia 1020. All you do is move your head to shoot down asteroids. Here, the focal length of the lenses is a problem, because you can't see the whole screen. But still, it was really fun to be able to move my head and look around in space, and shoot asteroids.
I'm really looking forward to seeing what we can do with these things.
