This light holder I created to minimize the space taken from all my office furniture and make cleaning simpler.
This adapter fits any Sit/Stand Desk leg with 8x5cm dimensions and the light post diameter is 3.1cm.

The screw that holds the light is 9mm  and the two black screws that hold the mainholder to the baseholder is specified in the second photo.
You can make changes in the model to fit your light and desk.

Happy printing!
