Orthanc
thingiverse
Tower of Orthanc - my edit has the balcony and staircase like from the movies, as well as a few other cosmetic edits. I printed these out specifically for War of the Ring second edition to pimp out my copy of the game! Looks great on the board, don't print too small or too big, but the bigger the better for detail.
