NEW! "Flexi-Tip" arms are now availableIntroductionThis is full Google Cardboard 2015 compatible VR viewer for the iPhone 6 or 6s* (6 Plus coming a couple of days) that is compact and portable providing a superior viewing experience to Google Cardboard and other viewers costing several times more since it uses the larger 37 mm lenses and the swing out slotted arms to ensure the optimal FL distance and alignment is met by sliding the iPhone into the slots.   The lenses can be purchased on eBay and Amazon (http://amzn.to/1ND9ZHa) for less than $7.  However, for superior experience, look for glass lenses. They cost about two to three time more, but the clarity is better, with less edge deformation and chromatic aberrations.  I should have these available in about two - three week, price TBD.I also plan to make these parts available through Shapeways with no mark-up if you rather go this direction. Or  available through my online stores as part of my NEODiVR line-up of eAVR enabled VR products as a finished rubberized product with "all glass" lenses.Please HelpIf you like the design and you make a pair for yourself. I need your help to produce a VR viewer for kids called the NEODIVRjr and to get 100 into children hospitals before Christmas.  You can pledge as little as $5 or up to $1250 and I will come out with 10 NEODiVRjr BASICs and provide full day of training and education on creating your VR environments for training, simulations or even for games.

You should require no supports in printing this. All STLs have been verified and made print ready and are oriented already for printing.  As in the title, PLA will work fine and preferred and most parts should print without any extra care in preparing your print bed.  Time to print all components is around three hours.  You may need to sand and finish the parts.  You should also run a very fine drill bit by hand through the hinge channels before attempting to assemble.Assembly Steps1. Glue Center Hinge Posts (2) to Lens Body. (Recommend epoxy, but super glue should work fine.)  Wait at least an hour before moving to step 2.2. Carefully push the straightened paper clip through the hinge pieces on the lens body and support arms. Clip the ends off flush with wire cutters. Add a touch of epoxy or super glue to prevent it from working out.  Verify proper rotation of support arms and not rotating out more than 100 degrees and folding flush against the lens holder bracket smoothly.3. Sand and file the edges, paint if necessary.  I use a rubberized coating and paint the trim by hand.  Check fit with the your iPhone 6.  Should fit snugly, if too tight, sand opening.  If you are using another phone, measure thickness and height and either sand, or adjust the STLs prior to printing.3.  Insert lenses in both lens holes until they rest on the small ridge at the bottom of the lens bracket. If the lens seems loose, add a drop of clear plastic glue.  The tolerance gap is .025 mm  Do not use super glue. and do not get it on the viewing surface.  It is recommended if your lenses come with a plastic protection layers, to keep it on until finished mounting the lenses.4.  Install the Google Cardboard app onto your phone and either use the default Google Cardboard setting (2015) or the provided QR code which you can print out and attach the outside of the arm.I have also attached a "paper" version of this that can be cut out of 60+ weight paper and create a super cheap paper version.There will also be a iPhone 6+ version of this in the next couple of days.
