This is a mod to a 3D Eiffel model I made last year for Tony. It's based on the tower in Paris, TX so not exactly the same as the French tower. It's scaled to 8" tall. I'd suggest cutting out the gray to get the tower shape, then use a spiral to the the impression of the girders and bracing in the structure. Or maybe wood burning for the bracing?
If you cut it, please post a photo.
