This is a phone stand that will fit most phones. It is wide enough at the bottom so that your phone will comfortably sit in it. The bottom is cut out so that it doesn't block any of the speakers or the charger port. Unlike most phone stands, this one is elevated off of your desk, making it easy to view your phone while you are working. It is stable and will not fall over easily while your phone is in it. Small tablets may also be able to be used on this if they are balanced properly.
I suggest printing with 2 walls, 15% infill, and .2 layer height with Arachne wall generator. I find that these settings make it strong enough to hold your phone, without using up too much filament. However, most printer settings would work with this.
Enjoy, and let me know what you think of this phone stand!
