I started with 42 gears, but, upon editing, was able to squeeze in an additional 20 (6-tooth, magenta) gears
 
42 large gears are identical (excepting color, of course)

• Yellow gears: 20 teeth, 12 count
• Cyan gears: 20 teeth, 30 count
• Magenta gears: 6 teeth, 20 count

Yellow gears aligned with icosahedron vertices • Cyan gears aligned with icosahedron-edge mid-points • Magenta gears (hard to see the color, down in between the teeth, I know) are centered on icosahedron faces

Polyhedral basis for gear positioning: Truncated triacontahedron faces

Large-gear rotation axes are aligned with the faces of a truncated triacontahedron, or looked at another way, with the vertices of a frequency 2v, class-I geodesic tessellation of the icosahedron

• Modeled in Google SketchUp
• 10 frames; rendered in Kerkythea
• Animated in Sothink SWF Quicker

You HAVE to 3D print this thing.

At the size I want (about 10-12 inch diameter,) 3D printing is, still, way too expensive.

I'm working on getting one of each gear 3D-printed, and using them to make molds & resin castings.

Ah i suppose that is true, albeit there are probably powder printers accurate enough to print it to something like 4 inches or even smaller but they're probably pretty expensive too.
If you're going to cast it (which is quite clever now that you mention it) i wonder if you could just make an aluminium casting which would be even cooler.

Wow!!!! Love it!!! It's super cool!!! I didn't know it was possible...lol [link]
I would really like to make this into a sculpture! Is it possible if you could show me the calculations you did to make this?

So sorry,

I, myself, am producing a couple of kinetic gear sculptures; this one and the 92-gear version.

You should note that I was originally inspired by early geodesic-gear attempts by another artist, Paul Nylander (~bugman123) and he has continued to further develop more of the math than have I.

I could stare at it forever, it's almost hypnotizing in its complexity :D
Great job! :thumbsup:

Indeed, it is rather hypnotizing!

Kinda makes me wonder why we all have a predilection for shiny baubles!

I wouldn't ever call it 'bauble' :D
It's more like 'Art'. You surely know how much kinetic art is expanding, this is a pretty original example :-)
