You can refer to the original for instructions.
But in summary, use a piece of filament or a toothpick (my case) to bind the clip to the mount.
Print the clip tall on it's “side" with supports
Print the mount body facing down the bed, no supports are needed
The author remixed this model.
I changed arms to make them thicker, since the original one (which is a great design BTW) broke 3 arms right away when I tried to fit my Wyze OG, other than that, most of the design is unchanged because it's already very good!
