The source model by CheeseJam has parts of the Eiffel tower thickened which is very nice. I had some issues, however, getting the lower structure to print correctly. So I spliced the upper portion with a different Eiffel tower model by Newcandle. The resultant combined model seems to work best for me on my Folger Tech FT-5. I suspect it might work well on other large formats like the Ultimaker Extended series, Lulzbot and Wanhao Duplicator 5S, etc.
