I wanted an Eiffel Tower for FFF (FDM) printing with some structural detail. And LEFABSHOP Famous Paris Buildings Eiffel Tower (https://cults3d.com/en/3d-model/architecture/famous-paris-buildings) was the perfect place to start. I imported the STL's in Fusion360. Then I copied the profile and added some texture detail.

I made the tower 150mm in height. It's not a good idea to make it smaller. Many of the tiny details have just 0.5 wall thickness.

It's modeled with a 0.4mm nozzle in mind for 0.45 wall thicknesses. Also you would need to add suppports in your slicer for the inner archs, but they are not needed under the surface textured beams.

I'm glad to read your comments and see your prints! :)
