Ahh, I see...got it. Actually, I could model each part and create that assembly in 3-D SolidWorks in under an hour (I'm an ME and I do this every day...) but I'm not sure how much good that would do, other than provide cool pictures! Unless you wanted to send the drawings to a machine shop, but I doubt that would be cheaper than doing it yourself.

I will probably try this whenever I decide to get lights, it's a very good design. Definitely post pics when you're done!
