EDIT:
The wings must be printed on 3 layers, otherwise the plane does not fly well. please check this out in BAMBU studio
The Airplane is printed upside down, after printing the model must be turned and the wings bent in the right direction
another version of the mini plane. the first layer must have a height of 0.12, for greater strength. other layers are set to 0.08mm. Bend the rear wings under approx. 45°. The large wings can also be bent. Throw the glider up, then it flies far, suitable for years of use even into the wind. I also added another print profile with all layers 0.12mm, but it's not as good
