The wings are designed to print using 0.5 mm width, 0.3 mm height, 3 bottom and 3 top
layers, but one perimeter only.
Should you print thinner walls, the perimeter of the upper side will not stick well enough
to the perimeter of the inner stiffening construction.
If you apply thicker walls, the perimeters will not come out continuously in one
The layers must build up as if you were printing in spiral vase mode. Only then you get a
smooth surface on the upper side.
If unsatisfied with the results, try out 0.49 or 0.48 width in your slices settings. It
depends whether you use Cura, Slic3r, S3D or what yo have. I suggest you experiment with
some tests before printing the whole thing.
The second point is: Should you print lesser layer heights, the inner stiffening
construction will not connect well to the top and bottom layers. You will suffer a gap in
