I made these Flightfin extenders for some people and figured I could just share the design with the world.

Yes, the bottom is flat and that isn't as nice as having a curve there as well.
The thing is, it is so much easier to print them like this and they will still work.

When printed in TPE/TPU the bottom will curve along the fender when mounted.
