Model Rocket Fin Can - 24mm Elliptical

thingiverse

This part is a set of fins integrated into a short section of body, that slips over a common model rocket 24mm body tube. The elliptical fin shape features an asymmetrical forward chord centerline, giving it a forward-swept appearance. Three and four fin versions are included. The fin size measures 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 seamless merge of the leading and trailing edges into the body. There's also built-in support for printing the trailing edge. That support should snap off easily, but it will depend on your particular printer and slicer. Versions without this support are included so you can try your own print settings. I can quickly generate five or six fin versions, and have some flexibility to scale the fin size. If anyone really needs something different just let me know.
