Seeing how well grandcross and Max Q's Saturn 1B projects are turning out, I thought, "why not try my own?" I started fooling around in OpenRocket and, after a bit of obsessive fiddling, came up with a reasonable design. The exterior (S-IVB) airframe is 3" in diameter, with the capsule and service module lining up nicely as BT-60. The first stage is a 29mm tube with 8 BT-20's clustered around it and will hold a 24mm motor mount. My "BT-60" and "29mm" tubes, as well as my motor mount, are tubes from paper towel rolls, etc. that I happened to have lying around. I haven't put together a paint scheme in OpenRocket yet, but here's a few pictures without it:

The build may take a while to get started because I need to do a bunch of part-gathering... I still need a 3" tube, and I'll be laser-cutting & 3D printing parts next week. I'm leaning towards either the Estes 3" tube or the Apogee thin-wall tube, which are about the same.
The other issue is that I'll be doing a cardstock transition for the petal adapter, which I haven't done before. If anyone has advice on making those, I'd love to hear it!
