iphone stand - angled for video watching

I designed the angle of this iphone stand for video watching or better app viewing (= the screen is more parallel to your face), my height is 1.80m and my gf's height is 1.50m and it the angle was ok for both of us.

Unfortunately this design is not ideal for facetime or whatsapp, as the angle will make your face not centred (it ll show at the bottom of the screen... you don't want that !). Prefer an other design if you use mainly the camera of your iphone for video chatting. (this one for instance : https://www.thingiverse.com/thing:4485514 )
