A 6 fin model rocket. Originally designed to be a short rocket to fit an Estes E size rocket engine. To fit an E size engine, scale the Y value within the maker software to be 150 mm. The rocket can be scaled down to fit a C or a B size engine as well. I've also provided an Inventor Assembly File if you'd like to make edits to the original, or check the scales of parts before printing. Made using Autodesk Inventor Pro 2014.
