I bought these lamp tripods for not having to drill holes in my walls to mount the basestations for my Valve Index. But when I got the tripods, I noticed the top part doesn't swivel. So I designed this adapter that you can screw onto the camera mount screw (1/4-20 UNC thread) and on the adapter you can screw the ball-joint that is on the plates for the basestations (see photo's).
The fit is a bit tight, but it works and solves my problem :).
