Water Rocket Fins

This is a remix from [@tstewy's](https://www.thingiverse.com/tstewy/about) [Soda bottle Water Rocket](https://www.thingiverse.com/thing:1794341). Me and my friends made these for a science fair. We needed to experiment so we made our own fins. We also needed to find how the fins affected the altitude and stability. Our research showed that the elliptical fin worked better.
