the first layer must have a height of 0.119 for greater strength. other layers are set to 0.08mm. Bend the rear wings under approx. 45°. The large wings must thus bend below approx. 10°. You have to bend or straighten the wings in different ways. Throw the glider up, then it flies far. The wings must be printed in 3 layers, otherwise the plane does not fly well. The plane is printed upside down, after printing it is necessary to turn the model and bend the wings in the right direction. You can also print my other models, which you can find on my profile
