None of the F35 STLs I could find suggested printing without supports.
I think being true to the concept of additive manufacture is to do as little as possible in post-production, such as removing support material.
I selected the moderately low-poly model at https://www.thingiverse.com/thing:860590 for its ability to be dissected horizontally with a very good chance of success of printing both upper and lower halves without the use of supports.
Print and lightly glue the two parts together.
Comments welcome.
