Happy to report I’ve used a tree data structure for the first time other than job interviews / college. SceneKit for iOS has a concept of nodes, and children nodes and parent nodes, etc. I wrote a recursive system to highlight the international space station 3d model when tapped. NASA provides a 3d model for free. It has lots of different components / levels.

Cool project here:
As well as Blender, I used Cheetah3d to apply the textures, and save to the proper format for use in SceneKit.
