OBSBOT Extendable Tripod Mini Ball Head

This ball head drops onto any 1/4 in male thread and gives a webcam or small camera full 360-degree horizontal rotation plus -90 to 90 degrees of tilt, useful for switching between landscape and portrait framing without remounting. A lock knob holds the angle once it is set.

At 56 g it adds almost nothing to a setup's weight, and the aluminum alloy body still handles up to 2 kg, more than any OBSBOT camera it would carry.
