Head strap clip for Google Cardboard

thingiverse

You'll need to attach a clip to the Google Cardboard so you can wear it without holding onto it. To do this, print two clips first. Then, insert them into the front of the headset between the two cardboard pieces, just like in the picture. Next, find an elastic strap that fits comfortably around your head - I used one from a headlamp. Make sure to orient the clip exactly as shown on the headset before attaching it.
