This is a model I created based on Ms. Radio an arcanist from Reverse 1999 I made during my time at school. I made this project while using Maya, which I no longer use. That's why it includes the relationship arrows, which are set to be hidden by default.
The package includes the Blend file, an FBX, and two images: one is the texture for the radio's symbols, and the other is the normal map for the ring. The model is fairly dense, so you may need to optimize it if you plan to use it in a game engine. Otherwise, it should work well as a rendering model.
