    "A comment says PLA in a partly closed enclosure got hot enough that the extruder teeth mangled it. calls that heat creep: the enclosure turns into a small oven and softens PLA before the hotend. That is a printing problem, not a rating for a finished box.",
    "A comment says black PLA parts on a printer enclosure had no issues after three years, and that the commenter is not dealing with temperatures above 100f or much load. The 100f figure is the comment. This catalog does not store it as a PLA limit.",
    "Polycarbonate's higher nozzle window is the polycarbonate page. Linking it does not mean these comments tested PC around a power supply."

    "The useful comments are split: a low-load PLA printer enclosure, and heat creep while printing PLA inside a closed box."

  "community": "The editorial summary says PETG or ASA for enclosures near heat and PLA for low-heat electronics. The excerpts do not name PETG or ASA. r/prusa3d 1107u40, score 27, says the parts were printed in black PLA, with no issues three years later, and that the commenter is not dealing with temperatures above 100f or much load. Score 15 says people who say PLA breaks easier should watch a video, and that it is not that clear cut. r/3Dprinting 105by21, score 25, says PLA is soft and that a partly closed enclosure made the extruder teeth mangle the plastic. Score 9 says it is probably heat creep, that PLA does not always print well in a hot enclosure, and that the box is softening PLA before the hotend and clogging the nozzle. No excerpt was supplied for r/prusa3d 1hge42l, r/3Dprinting uh31ws, or r/BambuLab 1gscyka.",
