print fell, the legs fell down and the printer kept printing onto nothing, so enjoy the spaghetti. Sometimes when moving around the nozzle can snag the parts and make them fall. Z-hop helps against that but it can’t do miracles. As VelvetStorm@lemmy.world mentioned, you need supports.

See the very small connection at the feet? It couldn’t support the weight of the leg as the leg angled away and cantilevered. So they broke off, but the printer has no way of knowing that so it kept on printing.
