The wings here are just little flat pannels, you can make them bigger (but still flat).
You'll find a bunch of parameters to set in the OpenSCAD sript.
Also, the code is broken in thousand very little modules to make it easier (?) to play with it.
Download, print, take a photo and click on "I made one" or... wait until I change the shape of the real wings or... both or none.
If you try this and find it hard to assemble, check out the ancestor for a tape trick.
