I quickly designed this Mavic Air controller stand / mount for my iphone 8 plus with UAG pathfinder case as my phone won't fit to the controller grip for its size. I also don't like the idea of flying the drone with me looking down onto the controller, so I made the extension arm to prop it higher above hand level.
The base is uniquely created to have a slight notch on the grip area so that it can securely hold on with the grip and base. Seen in the pictures. It also has a lanyard slot.
This system uses the gopro knob screws. If you don't have any, you can use M5 screws and nuts. The base uses four M3 x 12 (or 10-11).
If you have a different phone, you can easily change the size of the phone holder with the Fusion 360 file included (.f3d).
The STLs are already oriented properly to be printed as they should be for maximum durability.
Feel free to remix my thing as long as you link it.
