Ok, here's a best guess at the dimensions of the Camroc's nose cone.
My only tools (besides Open Rocket), were my knowledge of body tube diameters, and a metal ruler. This is only to give an idea of the outside appearance of the nosecone, and can't be trusted to be accurate for internal dimensions. I've broken the Camroc down into its basic external parts, and color coded them for clarity.
Left to right: Plexiglass Window (unseen), Nose Cone, Main Body Section, Film Block, Film Retainer, Cover, Adapter
To hold it all together, each joint between parts (except the plexiglass window/nosecone joint) was taped with what appears to be a 1/4" wide piece of yellow vinyl (electrical) tape.
And here's an idea of what it looks like all black:
I'm thinking that for a quick and dirty simulation (the diameters would be off a little), the larger diameter pieces could possibly be faked with a pieces of a
florescent tube protector, a BT-60, and some couplers. For the plexiglass window and the nosecone, I'm thinking of paper-mache over a balloon, and the clear window of a toy watch.
Of course, with a dimensional drawing, 3D printing would be able to handle the entire project. I've learned about a mechanical engineering club on campus, and haven't heard back from them yet.
Pointy Side Up!
