I recommend printing the 3mf file, using organic supports.
It is a windmill that does not use screws, all the pieces fit together.
For assembly, place the shaft in box 1 and cover with box 2.
use glue to join the box with the body and the body with the base, also use it to join the shaft with the blades
It is recommended to print with tolerance -0.5 to fit the box 1
