As shown the tower is 122' or about 17". Each tower section is about 3 1/4" so it can be printed on most printers and you can size it any height you prefer. The legs are hollow and I used 20ga bare copper wire to slide through them to provide power for the led on top. It takes a high detail print and some TLC handling as they are fragile. The Quonset hut glued to the tower provides stability. It is also large enough inside to place a small circuit board for the flashing beacon on the top.
