This is a replacement fin for a Lakeshore inflatable paddleboard. I've seen other boards with a similar design so this may fit other paddleboards.
Improved the fit in the back.
Enlarged the fin.
Flattened out the front a little bit so it doesn't hurt your hand when pushing it in.
Posted Slic3r picture of new version.
Fin pictures are from version 1.0.
I used 100% infill just so it would be very strong. I'm sure you could use less though. It might be nice to use less so there is air in it which would make it float.
