The old TV stand was only build to turn about 20°. Obviously that is all you need for such an application. But I figured that the overall design might be suitable for converting it to do a full rotation. There were a couple of obstacles like an incomplete inner gear and some other hardware endstops that had to be removed. I used my phone to make an image of the assembly and used that for an attached canvas in fusion 360. After 3D printing a new inner gear I just had to glue that into the part in order to get a full 360° rotation. A video documents the entire process of this project :)
