Hybrid VR Headset

2015-01-16 VR HybridYesterday I completed the Google Cardboard Virtual Reality (VR) headset and mentioned I was planning to try a simplified hybrid version that would incorporate 3D printed components. Well here it is after a morning of cutting and printing!

One of the problems I had with cutting the original Google Carboard was the difficulty (and pain!) cutting all those small details, slots and holes by hand, eventually using a Dremel to carve out the eye holes (check out my original by clicking here). I have also been looking through the designs on Thingiverse to 3D print, however can’t find a design that seems properly thought through and doesn’t include unnecessarily chunky sections of material that seems wasteful (yes just another bit of motivation to get onto designing my own). However the adjustable arms many designs feature seems useful to optimise user experience for individual eye width, focus etc, and to improve visibility of the phone screen.

I have downloaded and 3D printed just the arms from the OpenDive Headset, which perfectly fits the 25mm lenses I bought on Ebay. Something else I’ve realised through printing is that if I were to 3D print the full headset, it wouldn’t fit onto the small print plate of my Up! Plus 2 3D printer with it’s 140mm maximum dimension. I would either have to slice the model in half and glue together after printing, or print on a larger printer (which reminds me I have still not heard anything about when my Solidoodle Press will arrive, and has the larger print size I would need! Check out my little rant by clicking here).

2015-01-16 Google vs HybridI have also significantly simplified the design of the Google Cardboard template to suit the thick cardboard I’m using and 3D printed adjustable lens holders as shown in the images above. This new design was significantly quicker to cut!

Overall the completed design is nice and easy to make, provided you have a 3D printer on hand. I’m getting a much clearer view of the phone without anything obstructing the lenses, however it takes a few minutes to get the positioning of the arms correct for your eyes. If you look closely at the top images you’ll see I used a sharpie to mark a line on both the cardboard and the lens holders where the optimal position is for my eyes. Like last time I’ve also used a small bolt to hold it all together, and used my 3D printed ‘edditive’ logo to stamp onto the cardboard (which you can read more about here).
