Lasercut Google Cardboard 3D VR glasses

thingiverse

A rugged, lasercut set of Google Cardboard VR goggles for 25 mm diameter bifocal lenses with 45 mm focal length. Optimised for a Samsung S4 with S view cover, since that is what I currently use. Can be hacked by simple means to fit other phones. Ready for a simple head strap, with strap locks included. I haven't got any straps lying around at the moment, will update the gallery once it's in place. The magnetic switch is not yet incorporated into the design, it may come later. It doesn't really work well on the cardboard original, and these ruggedised goggles were made to demonstrate cheap, hackable 3D technology for visitors at work, using some of the roller coaster demos that are freely downloadable at the Google play store. Use 3.2 mm (1/8 inch) material. I usually go for MDF, because it's dirt cheap, yet sturdy. Instructions The glasses are based on the original Google PDF that can be downloaded from the Google cardboard site. I nicked the lenses from a pair of Cardboard goggles that I bought on eBay. You'll need two 25 mm bifocal lenses with 45 mm focal length for these goggles to work, otherwise you're in for a bit of a disappointment. You'll find them fairly cheaply at eBay. The rings for fixing the lenses in place have pre cut holes for small screws (about 2 mm diameter screws). Added these so that the lenses wouldn't get nicked from our exhibition at work. You may just want to use glue. I'm using glue AND screws. There's not many parts to glue together here, use the pics for reference. There are two small frame parts on the inside that need to be mounted the right way around. I've made room for the irksome home button on the S4, which was a surprise problem on my first prototype. A phone restart is not as much fun as a virtual roller coaster ride. This may be a potential problem on other phones, but I think I left enough room for most designs. There's no magnetic switch, at least not yet. I may add it later, but frankly I don't think it works that well on the original Cardboard. A Bluetooth game controller is probably the best way of manoeuvring in VR environments anyway. Hope you have fun with these. I do.
