Turns your Android phone into a stereoscope. This thing is mainly for people with high-degree myopia. If you have normal vision then you'd better stick to original OpenDive (http://www.thingiverse.com/thing:96878).

Print all 3 sections then screw them together with M4 bolts and nuts. Middle section needs supports. The other two can be printed without supports. You may want to change length of the middle section. It will have to be longer if your vision is better than -10D or shorter if your vision is worse than -10D.
