Well, it just failed again, about a minute after this recording. You can see through the thin part of the base that a fairly significant portion had already detached. It got considerably further, though, so my adjustments were working, they just weren't enough. I'm going to slow it down a lot more and give it a wide, brim around the bottom. Hopefully the extra surface area will keep it stuck on long enough to finish. I might switch to a different filament, this one is very bright.
