PocketCardboard

thingiverse

This is a compact, two-piece VR viewer designed specifically for mobile devices. If you're not familiar with Google Cardboard, check out the official website: https://vr.google.com/cardboard/ The pocket-sized version should work seamlessly with most cardboard apps and can be controlled by tapping the screen instead of using a button-lever. I created this design from scratch as part of a 3D printing contest. Although I didn't win, it was an exciting project that allowed me to experiment with new ideas. During its development, I shared some interesting apps that worked well with my phone, a 1st gen Moto X: https://twitter.com/PrintedVR When setting up the viewer for the first time, you may need to point your camera at the QR code included in the Thingiverse files. This code embeds essential information such as the distance between lenses and whether screen touch input is enabled. You can find these files here or on the right-hand side of this URL: http://virtualme.github.io/PocketCardboardGetStarted.png Instructions: To assemble the viewer, you'll need a pair of 25mm diameter biconvex lenses with a focal distance of 45mm. These can be easily found on eBay or Amazon by searching for "cardboard lenses." You will need to print one lens kit (a model that includes "Lens" in its name) and one spacer clip. Then, you can either wedge the lenses into place if they fit snugly or secure them with superglue. Once the lenses are fixed, slide the spacer clip onto the lens kit until it clicks into place. Use the S-Clamp on the spacer to hang it over your phone. Open a cardboard app and start exploring! You can use the small tab on the end of the spacer clip to unlock its position and remove it when you're done. When choosing which size to print, consider the following: I initially used the 250 um lens kit version in PLA on an Ultimaker 2 with great results. However, I later encountered issues with different printers and materials, requiring me to file away the opening or even glue the lenses in place. To achieve consistency, I recommend printing a 260 um opening and securing the lenses with superglue. For the spacers, the numbers represent the distance in mm across their narrowest part. I found that size 10 worked well on my 1st gen Moto X with no case or a thin case. If you need to make adjustments for your phone's thickness, try sizes 7, 13, or experiment with other values.
