29mm Model Rocket Airfoil Fin Can

thingiverse

This is a carefully designed airfoil fin for a 29mm diameter model rocket propelled by a G-class motor. To achieve optimal results, I strongly suggest printing it "upside-down", with the leading edge of the fin positioned on the bed. The tips of the fins may become droopy due to excessive speed or weak support, so you can try slowing down the print speed or adding a column alongside each fin for added stability.
