Surfboard Fins for Thruster

Glass on fins for a surfboard. Total hack amateur fins, no high-level thought went into the design. I just wanted to make my own.

The tab is on there just for glassing. The other design was going to be a Future Systems compatible design but I decided to just glass on the fins rather than try to put in the fin systems.

The fins I've been using are about 6.5mm in thickness, This print is 4.5mm and needs to be 5.5 to get the correct thickness. Just scaling up for now but will upload a better design as I get one.

The picture compares my Future Systems fin to a fin I printed and glassed. See the instructions for what I did to finish this off.

This first fin is a little small/thin. It has too much flex, and I think the thicker part needs to be closer to the front to produce a good foil. Will keep posting as I refine the design.
