UFS-170 Ultimate Most Accurate Eiffel Tower for Its Size 20cm - 8 inches

New improved version for 2026. It is broken into three parts. Currently recommend scaling 160 percent or more, and use 0.3 nozzle settings (hint use 0.3 even if your actual nozzle is larger) especially useful for the middle section. The railing is very thin and hard to print. Turn off Arachne and use Classic for line width. 

Avoid supports if possible. That is why it is broken into three parts for easier printing. The pictures are for the parts printed without support. If you need support then add them only in select places. Model is delicate and supports can be hard to remove, resulting in you breaking parts off. 

I've added a new curved banister on the first floor, I redid the very top observation level, and I made some minor changes to the base. It looks great, and I finally tried printing myself. It failed multiple times. I think I was having heat creep and my nozzle was plugging. I reduced the retraction and lowered the nozzle temp 10C. Finally I got everything to printed with all the details.

This is a challenging print. The details are thin and there are a lot of columns. Print at your own risk, but send me your feedback. Thanks.

Improved design to be more accurate to the real Eiffel Tower. Also broke it into three parts to make printing easier.
