Found an even simpler way! If you have a bigger clip and a medium one, you can put one below and one above the phone to hold it in place. Clip them onto the mic stand from the side facing you and then you don't even need the small paper clip to hold the arms in place.
Awesome hack, my dude! Very resourceful, and frankly, it’s just cooler making my own things than buying the things that everyone has. Know what I mean? Cheers man! Edit: subscribed!
