How is thin unssuported wire defined? Or to be more precise, which are the limits? There are some rules about FUD, but not SF. It's just a wire hanging, not a load bearing wire. The item has been printed multiple times before, counting the part that repeats, it makes hundreds if not thounsands of wires. And of course, the reject was by 0.02 mm (face to face vs edge to edge distance difference in a tube).
