I also don’t know what Bambu will say but when I look at your UFO, although I believe it’s a string held up magnetically, from the photo it looks like a rigid wire. If I was a good EO I would look carefully and check the design files, but if I was just going by photo I might assume it was a wire.
Of course, the real answer is that competition rules will be poorly enforced and flooded with AI, and who knows what is allowed? I am still upset over the “battleship” competition, in which almost no one knew what a battleship is.
I don’t think there’s anything morally wrong when the rules say “you can use your own self-designed magnetic levitation components or the Magnetic Levitation DIY Kit”
