I've gotton a Mavic Pro, and used this item myself.
I found some inconvenience, so I created a new version.
I recomend to see and download the new version.
It is a foldable tablet holder that emphasizes portability.
We need a mobile device holder made by DJI.
It is more convenient if you have a minus screwdriver bit of 50 mm in length.
I designed this item using Blender Ver. 2.76.
You can also download design files, so you can improve it.
Base Part: 20% , Others: 100%
I printed with Polymaker PolyMax(TM) PLA.
The arm part is thin, so it's recommended to print with a strong filament.
