it's difficult to see what you are trying to achieve as we only appear to be able to see one layer...
have you tried support on build plate only?
have you tried printing the parts rotated 90 degrees so that the hinge pins are horizontal rather than vertical?
I try to make suggestions that I believe to be well founded and safe,You should understand the context and ensure you are happy that they are safe before attempting to apply my suggestions,
what you do, is YOUR responsibility.
