Very nice!

Very informative, too, which is very much appreciated! I must remember that "edge to spline" trick. Simple but effective to get those UVs from the modified bells.

I'd like to learn a bit more about the way you are modeling the command capsule, your approach sounds both interesting and useful for building objects like these. That first screenshot shows simple polygon objects defining the rough shape, right?

You say that you then used B splines to create the actual curves. I'm not quite sure how exactly you do that to get the shape shown in the second screenshot. Do you build a spline cage to get that object? Could you describe that part in more detail, and maybe post a couple more explanatory screenshots?
