So I am brand spanking new to 3D modeling, but my first crack at it is far from humble. I am using Wings3D to create this.

Attached is my general idea in MSPaint (nowhere CLOSE to accurate), the final product will maintain ALL Keplerian elements: Semimajor Axis, Perihelion/Aphelion, Eccentricity, Inclination, Argument of the Ascending Node, and Argument of Perihelion. I will be positioning each planet along their orbit at their position on 1/1/2000.

I decided to include all satellites that are considered to be of planetary mass, or close to it. The size of the planets, as well as their moons and respective orbits, will be on a different scale that I will determine once I have the framework complete.

First plate will be at a 1 AU:2 CM scale and will have Mercury, Venus, Earth (with the Moon), Mars, Vesta, Ceres, Pallas, and Hygiea. It will be at maximum 12.5cm x 12.5cm.

Second plate will be at a 1 AU:0.7 CM scale and will have Mars (with the inverse cone struts connecting to Mars above), Jupiter (with Io, Europa, Ganymede, and Callisto), Saturn (with Titan, Mimas, Enceladus, Tethys, Dione, Rhea, and Iapetus), and Uranus (with Miranda, Ariel, Umbriel, Titania, and Oberon). It will be at maximum 27cm x 27 cm.

Third plate will be at a 1 AU:0.2 CM scale and will have Uranus (connected above via the inverse cone), Neptune (with Triton and Proteus), Quaoar, Varuna, Salacia (with Actaea), Orcus (with Vanth), Ixion, Pluto (with Charon), Huya, Chaos, Haumea (with Hi'iaka), Makemake, Eris (with Dysnomia), and the unofficially named "Snow White". It will be at maximum 23 cm x 27 cm

And I've decided on a Fourth plate so that I can make Sedna fit reasonably. It will be at a 1 AU:0.5 MM scale and will have Eris (connected above via inverse cone) and Sedna. Sedna's orbit will be a disc, instead of a torus, and will serve as the base of the model. It will be at maximum 28 cm x 54 cm. there will also be a pole running through all the midpoints, for stabilization and generally to represent the Sun's position/influence.

I decided on using these particular planetoids based heavily on Mike Brown's studies as to which TNO's are most likely classifiable as dwarf planets, as well as which ones have been assigned names by the IAU.

The big question is: how thick should I make everything (I was thinking 5-7 mm), and how/where should I put the support struts?

Lol yes I forgot Uranus, to much tittering on Google+ ;p. That was just a quickie mockup to help visualize my idea. I'm hoping to have something real in the next few days to present

OK I managed to make the inner planets! You can see it so far here. The next part is to make support struts for them and label them.

So... who knows where I can go to learn how to make support struts and manipulate text in such an environment? I am as n00b as it gets to this, only downloaded 3D rendering software last week.

You might want to use more geometry in your orbits: if you look at the Shapeways render of your model you will see that they are faceted. I.e. instead of circles/ellipses/whatever they are polygons. At the size you want to print you will need many, many more faces to make the curves seem smooth.

Good point, the next iterations I'll jack them up

I always turn to YouTube for tutorials about anything, you will be surprised on how many knowledge you can find there.

Just search for "Wings 3d" and you'll find a lot of teachers, the best part is that when it's going to fast you can rewind unlimited times Very Happy It's like having a robot teacher that knows everything and has all the patience in the world !

OK, Alpha version of the first layer is uploaded here! This one is not meant to be able to stand on its own, but I DO want the struts to be viable, and for the labels to be visible. I'm going to go ahead and print this to see where I stand, but what do yall think?

And here it is, version 1 of the Dwarf Orrery project! Thoughts? I think it should be stable now, and I made the fonts a lot larger.
