Also check out my other Vario Lynx parts in my profile.
Sliding cabin doors and scale static cockpit doors for the Vario Lynx fuselage.
Cabindoor01/2 - Right and left cabin doors with standard window location.
Cabindoor01-mk88a - Special left hand cabin door with the window moved aft, as on some Lynx models (Germany Mk88a for example).
Doorrail01 - Fairings over the cabin doors which build out to make room fot the C-shaped rails.
Lowerrail01 - Lower rail for the cabin doors.
Cockpitdoor01 - Scale cockpit door frames.
The cockpit door frames need to be formed to fit the curvature of the fuselage after printing. I recommend cold forming.
The main cabin door lower rail should be secured with #0 countersunk screws in the five lugs, and glue in the front.
The main cabin doors need two #1 screws in the top which will slide inside the top C-rails.
Use M2 screws to secure the door handles and emergency release handles.

Print the cabin doors without infill and all other parts solid. Use supports in the window openings of the cabin doors.
