This is a mounting adapter to mount a webcam to a cheap USB powered LED ring light. I use this for streaming traditional drawing.

I sized this for my particular webcam and LED lamp, but yours may differ in size. You can customize this model to fit your lamp and camera using OpenSCAD. The model in the files is sized for a webcam using an M4 mounting screw, I used M4x10. I used an M4x15 screw and M4 nut to mount the adapter to the ring.
