I've made this scale 1:5000 pendant of the Berlin Fernsehturm (television tower) back in October as an experiment to see how thin wires would hold, but also as a little present for my girlfriend who originally is from Berlin. I've had it printed 3 times and with all of the models the top part was quite warped. This was the only one where I've managed to bend it back to a straight (ish) antenna. So I wouldn't recommend making long wires this thin (0,8 mm) But than again, you're not even allowed to anymore
Sorry for the bad quality of the images by the way, it was dark...
