Following the tradition of test-driven development, I've been making a collection of OpenRocket models to use as test cases for trying out center of pressure and stability calculation algorithms. Some of these are real rocket designs, some of them are simple geometric shapes that have interesting properties, and some of them are specific attempts to examine interesting corner cases.
Now that I've got a collection, I figure I'd start posting them here in case anyone else is interested.
My interest here is only in understanding stability estimation, so although a few of these are flyable designs many of them don't have proper materials, wall thicknesses, masses, internal structures, etc assigned. In many cases the only thing that matters for my purposes is the surface shape. So don't try to interpret things like the Center of Gravity in most of these.
I'm also not currently thinking about drag coefficient estimation or altitude determination, only stability, and I'm also mostly focused on sub-sonic low Mach number behavior.
So here's a few to start...
