missing a section in design

[bhavinpatel.31]

Hi, I downloaded a project from Printables, but there is a missing section in the component, I have attached a picture and project file. the yellow gold section is the internal surface but there is no external surface, could someone fix and/or tell me how the outer surface should be added.

Thank you!
