Creating fins on various surfaces with different normals more efficiently

[serabouch]

I want to generate fins on 4 surfaces with the same dimensions. The way I am doing it is by isolating each surface within the list and generating the same fins independently for each surface:

This doesn’t seem efficient and only works for these 4 surfaces.
I would like a way for a simple script that would do this on any surface, not necessarily one that is on the xy plane.

Any ideas?

Data trees Some “fins” face in, some out because of flipped surface normal vectors.
