USS WoodenPrize (StarTrek Themed Ship)

We had some old wooden moth rings we were gonna throw out. I was inspired. So I made a model to turn them into a StarTrek ship.
The wooden rings were approximately 46mm in diameter, 9mm thick, and had a 12mm Diameter hole in the center. ( I included an STL of the approximate size/shape. )

It should just snap together around the wooden piece. No glue needed if tolerances are good.
