MakerWorld answers an expired or missing auth token with {"error": "Please log
in to download models."} and no download link, which was skipped without a
word, so imports and "Download files from source" just ended with no files.
Now the reason comes back: missing settings, a refused token (probably expired),
no printable files on the page, or a failed download. The import screen shows
it, and the Settings hint explains where the token comes from.
