Ever since I got my 3D printer, I've always wanted to print this Eiffel Tower model: http://www.thingiverse.com/thing:22051
However, due to my nozzle size and total build volume, I could not slice/print some of the smaller features. So, I found the source SolidWorks file (https://grabcad.com/library/eiffel-tower) and slightly enlarged every small feature my slicer wasn't recognizing.
I had to print this as big as possible for it to come out right on my printer (about 6in/152mm tall) using my 0.5mm nozzle. If you have a smaller nozzle size than 0.5mm, you may be able to print this even smaller. It was a very hard print, but it came out pretty well!
Need 0.5mm nozzle size or smaller when printing the model about 6in (152mm) tall. A smaller model height may be possible with a smaller nozzle size.
