Spark/Mavic "GO" universal tablet holder

The previous tablet holder what I designed, has the advantage of portability, the difficulty of assembling time and its disadvantage.
Now I designed one that is less portable, but ready to use with two gestures.

My other designed holder: https://www.thingiverse.com/thing:2899878

Except for the universal tablet grip (2pcs), no support is required.

There are two nuts in the two clamps. This is when printing at approx. Layer 30 should be inserted. After that, they can no longer get lost.
