This is a universal holder that can use any smartphone as a camera on a tripod.
You will also need the tripod attachement counterpart provided with this holder.

Techincally is a breadboard ridded with holes and a central cut out small enough to stop any smartphone from falling out through it, large enough to accomodate full camera view unobstructed for the phones mounting the camera close to the center, the phones mounting their camera at one corner can be used as well placing the camera above the mount margin.

Locking the phone to the support is done by using 3 or 4 of the mushroom head locking nuts and a M4 bolt for each of them passed through the hole of your choice in the breadboard, use of large washers is highly advised.

For the price you get the smartphone holder breadboard, the triopd attacheemnt piece and the locking knob piece STL files to print on your own 3D printer.
You need to source elsewhere one M6 bolt long 100mm, one M6 nut (you can use imperial apropriate size too) 4 M4 plastic inserts and 4 M4 bolts long 30mm (or apropriate imperial equivalent).
