Pershing II Model Rocket Fin

This is a fin for a Pershing II model rocket. I previously designed the nose cone for the rocket and I finally took the time to make the fin so that I can finally assemble the complete rocket. You can modify the openSCAD program and enter the diameter of the body tube you will be using for the rocket. From that number, the program will scale the fin to the proper size and even print out the length of the body tube you will need for a scale model.
When I first printed out one of these fins, I noticed that they were quite thin, so I provided a mechanism to increase the thickness. The variable extra_thickness is used for this purpose. If you make it 0 you will get a scale fin. Increase the value and the fin will be thicker and stronger. I would recommend trying different values until you get a nice looking print.
