Speedy "Red Midi Swept Wing"

thingiverse

This is a forward swept wing which you can use with the fuselage of the “Speedy Red Midi Wing” https://www.thingiverse.com/thing:2386440 The carbon rods pass all the way through, providing extraordinary stability. You need one 8 mm tube and one 5mm tube, each 1000mm long. These rods are so stiff and fit in so tightly, you don’t need to glue anything. This makes changing a part very easy, in case it is broken or you want it in another color. I havn’t had a chance myself to maiden it yet. Recommended Print Settings Attention 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 uninterrupted turn. 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 between.
