Model Rocket Fin Can - 24mm Elliptical

thingiverse

This Thing is a fin can (fin can = set of fins integrated into a short section of body), that slip fits over a common model rocket 24mm body tube. The elliptical fin shape incorporates an asymmetrical forward chord centerline, giving it a forward-swept appearance. Three and four fin versions are included. The fin size is 100mm root chord with a 40mm semi-span (not including the body). Each fin is tapered spanwise and toward the leading and trailing edges. Full fillets are included that also taper to the leading and trailing root edges, as well as a graceful merge of the leading and trailing edges into the body. There is also a built-in support for printing the trailing edge. That support *should* snap off easily, but that's going to depend on your particular printer and slicer. Versions without this support are included so you can try your own. I can easily generate five or six fin versions, and have some ability to scale the fin size. If anyone really needs something different just let me know.
