This iPhone 4 horizontal stand is suitable if you want to use your iPhone as webcam or if you just need a very firm and stable horizontal stand for it.
Front and back camera have free sight and the 30-pin connector, home and on/off buttons are accessible.
I made two versions (V1, V2): The difference is, that V2 has addional cutouts for the headphone-jack on the top and for the mic/speaker on the bottom.
Remark: If you look at the one I printed, the pocket for the front camera looks a little bit too small. Indeed it is, even if just very little! However, both stl files have already been corrected and have large enough pockets.
Don't hesitate to drop comments, if you need some adaptations.
