The Castle from the movie Howl's Moving Castle. If you haven't seen it, again I recommend you do.
The largest file "HMC To.stl" measures 207, 111 with a height of 194 mm. I printed this file without supports. At .15 mm layer height, the file took about 44 hours to print.
The only file I used supports on are the ears.
You can try to reduce the scale some if want. Check all of the parts in your slicer to make sure they will print first.
Don't forget Calcifer and Turnip Head!
