Print Settings
Attention
The wings are designed to print with 0.5 width, 0.3 hight and 2 bottom and top layer
If you print thinner, the perimeter of the upper side will not merge with the perimeter of the inner spars.
If you print thicker, the perimeter will not be printed continuesly in one turn.
The print must go as if you print in spiral vase mode. So you reach at least a smooth surface on the upper side.
If needed, you must try with 0.49 or 0.48 width. It depends on which slicer you use.
The second thing is, if you print with less layer hight, the inner spars will not connect the top and the bottom layer. There will be a gap inbetween.

All parts: layer height =0,3mm, width =0.5 mm
wing
1 perimeter, 2 bottom layer, 2 top layer, hollow
wing servo: 2 bottom layer, 2 top layer, hollow
aileron base: 5 bottom layer, spiral vase mode
aileron end: 2 bottom layer, spiral vase mode
aileron appendix: 1 perimeter, hollow
aileron interface: no bottom layer, spiral vase mode

fuselage
fuselage front: 7 bottom layer, 3 top layer
fuselage back: 3 bottom layer, 3 top layer
fuselage interface: 2 perimeter 0.4 no bottom/top layer, holow
fin: 4 bottom layer, spiral vase mode
fin cover plate: 2 bottom layer, hollow

The part "elevon_base_right_2.65.stl" was a wrong file!

Instructions

All sections of the wing are only hold together by two slightly elastic plastic cords inside the tubes.They are fixed with luster terminals on the wing ends.
There are only short joints to connect the parts.

Connectors 4 mm carbon tube
The holes for the connections are only parallel:

  1. In the middle, between the wing_center and the two wing_middle_rigth/left
    (50 mm in each side of wing_middle, 200 mm total at front tubes)
    (60 mm in each side of wing_middle, 220 mm total at rear tubes)

  2. At the servo segment
    (45 mm in the middle_wing and 25 mm in the wing_right/left (110 mm total at the front tubes)
    (50 mm in the middle_wing and 75 mm in the wing_right/left (165 mm total at the rear tubes)

  3. At the wing end
    (30 mm in the wing_right/left and 30 mm in the wing_end_right/left, 60 mm total)

The pipes must not be inserted deeper. There the holes bend and break very easily if you go deeper!

If you have to split the wing sections, the connectors will not be parallel, that means, you have to plug in the tubes one after the other, and see that you can get them out again, if needed. If both pipes are inside, the wings can not be pulled apart!
