Thanks again for the valuable feedback! I printed it again with higher temperature, 240. It didn’t change much, overall. Same print errors remained, however I got a few less of broken hexagons, so overall the print feels more sturdy.

Looks like the majority opinion here is to blame that all on wet filament. I don’t have the right equipment to dry it, so I’d probably just avoid printing similar parts with this spool, and take more precautions when it will be time for a next one. My drybox spool holder build is almost ready.
