And that's why you always print with supports.

Supports wouldn't have helped here. At least not automatically placed supports.
What happened here? Was it too much weight? Was the bed too hot?
As OP, I'm curious too 🤔 Do we have 3D printer expert here? @[email protected]
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 [email protected] mentioned, you need supports.
Unless you are printing something that is basically just a horizontal sheet like a lithograph, you always need supports.
Thx, so I researched it a bit; so Z-hop means little up-and-down movement between the parts and "support" is literally an extra part independent from the main part, used for support, if I understood correct.
I watched the video again and it seems that the problem is not due to the foot falling, but in the part where the two legs join 🤔
I kindly disagree, I only add supports when there is an angle bigger than 60°. It depends on the printer, I tested mine and 60° is the limit.
And about this video, now that I think about it, maybe the octolapse or whatever software that made the video probably touched the piece when it got into place for the screenshot, and made it fall.
Ironically if the video was not taken, the piece may have come ok.
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.
