This is an interpretation of how it could looks like the homeworld of the Gem race in Steven Universe show, usually referred as "Homeworld" or "Gem Homeworld", based on the first overview of this world in the episode "Legs From Here to Homeworld". There is a hollow and a filled version. The files, apart for the "hollow" models, are suited for 3D printing, but no for the assembly of the parts; that is, the rings has no support for mounting.
There is no real clue of the size, mass, nor nature of the system in which it is located. It is clearly hollowed in some way, like the Gems' final stage colonies. I first speculated about it size assuming it may be a white dwarf heavily exploited by its inhabitants, I made several guesses about the mass, the porosity and it gravitational attraction. However, when the Steven Universe TV movie came out, It could be seen, in the start credits, in an old-cartoon-style story book, that there was a comparison between Earth and the Homeworld. Although it is never said it is scaled, I take that as the most official reference to its size, being approximately 26% bigger in diameter than Earth.
A ring system with two oblique rings that close to each other is far impossible and unstable. Also if you measure them in the original picture, the outer edge of the inner ring is wider than the inner edge of the outer ring, so they overlap at least in one place. When I made the complete reconstruction following the original image I have to put the inner ring displaced from the center of mass (the center of the model), which is also impossible. One explanation could be that the inner ring is composed of ferromagnetic material (iron), and it is orbiting around the magnetic dipole. This is pure speculation, I don't know if it works like that. The magnetic poles are far displaced for the axis of rotation, since its irregular shape. The particles in a ring could be meters long, and separated by many times their sizes, so in the part that the rings cross each others, the particles could have little interaction, with occasional collisions. The bigger ring, that orbits the center of mass and is composed only of non-ferromagnetic bodies (stony and carbonaceous), suggests in which direction is the axis of rotation.Â
