The Joby GorillaPod 3K Kit (plastic) is generally suitable for cameras weighing up to 3 kg. As the Nikon Z 6 II has a weight of around 675 grams (body), this tripod is perfectly suitable for this camera.

However, it is important to note that you should make sure that the camera can be attached to the tripod head of the GorillaPod 3K Kit, which is usually possible through a standard 1/4" screw used on most cameras.
