I used this https://github.com/guillaumef/openscad-airfoil
To generate the initial shape.
I then added holes for 3mm carbon tubes, and some triangular supports.
And then used this: https://github.com/OskarLinde/scad-utils
to 'fillet' it and round everything.
I have not had a chance to print it yet but will update when I do.
