We're back with another Google Cardboard modification. The cardboard is amazing, but having to hold it on your face is a severe hindrance. Several games available require the use of a bluetooth controller, and having to hold the goggles makes this impossible. This is our version of a headstrap.
Google Cardboard, sharp cutting implement, 10-12 inch (25.4- 30.48 cm) of 0.25 - 0.5 inch (0.635 - 1.27 cm) wide elastic strap (check art stores)
Stapler, sewing machine, needle and thread,small plastic side release buckle.
Step 1: Measure and Cut Slots
Measure 1.5 inches from the bottom of the of the cardboard. Measure 0.5 inch in from the outer edge. Using a box cutter/scissors/sharp knife etc. cut a 3/8 inch slot in the cardboard.
The height of the slot is dependent on how wide your strap is. Our strap was 3/8 inch wide ergo, 3/8 inch slot. Additionally, our hole looks really ragged because this set of goggles has had the strap taken in and out many times.
Step 2: Secure Your Strap
This is where some different options are available.
For those looking for the simplest method, thread the strap through the two slots, and tie a knot to hold them. Example: Picture with yellow strap.
Something just as easy to do is to staple the strap, but it might lead to the strap tearing later down the road. Thread the strap through, and staple the overlap. Example: Picture with white strap.
For those slightly more ambitious and with a sewing machine or needle and thread, you can sew the strap. No example picture provided.
If you want a non adjustable strap, make sure you test fit it against your head and use the right length of strap. Stop here.
If you want an adjustable strap leave an extra 1.5 inches on the strap and move on the next step.
Step 3: Attaching a Side Release Buckle
At this point, you should have a strap secured on your goggles. Now, take a deep breath.......and cut the strap in the middle. Don't Panic. You should have a buckle like the one pictured, secure one end of the strap through the side with one slot, like the example picture.
The second part is a little trickier. Our strap had a coefficient of friction too low to securely hold it in place through the normal method of securing the strap. If you examine the example picture, I threaded the strap through the first slot 1., around to the second 2., then back into the first 3. This causes the strap to lock with itself. It will tighten with no problem, but loosening it will be a little harder.
At this point, you should have a strap with a buckle. Hold it up to your face, click the buckle, and tighten the strap.
You should now have a working headstrap. Feel free to put any questions in the comments.
