FYI if you live in China, you can buy a kit (including machine-cut cardboard, velcro and lenses) for <50 RMB ($8). Magnets and NFC can be bought cheaply from other taobao sellers.
I made one by hand myself, and bought kits from two different vendors.
- the one I cut myself works, but it looks like trash and is not durable. Also, the lenses I used distort too much
- the one from the first vendor is great. The design has been modified so that the lens holes are a little wider, to accommodate the wider lenses supplied: http://tb.cn/qdMexXy
- the one from the second vendor was almost as good, but the doesn't have the slightly wider lenses/holes
If you're using an iPhone, I recommend the app '3dtube' for watching 3D videos. Also, search the App Store for 'durovis' to find other compatible apps.
Neat! If you don't live in China, you should be able to buy them from the usual places like Aliexpress and eBay for a slight markup. Looks like there's a handful of people reselling them. (Some stuff doesn't make it over but the more consumer-oriented stuff usually does.)
