After test it in flight field, I added three improvements:
1.- The lower part is thicker.
2.- Added lateral supports to avoid bending outwards.
3.- Added supports in the base to prevent it from turning towards the back and forth.
4.- Added support in the base.

Repair some errors in STL file (surface closed).
