All right, I think you are right on the curling upwards. I started another print, which is also using similar hexagonal sides, but is more massive - hexagons are larger, and walls are thicker. And it warps up visibly! When these overhanging arms on upper part of hexagons start printing, they just warp up while cooling. Then when nozzle comes back for the next layer, it hits the warped edges, pushing filament to the sides and making these artifacts. It didn’t break any segments, as they are thicker, but I bet that’s what happened in the original print.
On the new thicker print, the base of the model lifted up from the bed on one side at some point. I was watching the first two layers, so this happened some time later. Gonna try to slow down the print, lower nozzle temp a bit, bump up the bed temp a bit. Will see what happens.

But… but… but they are pretty!

Thanks! I’m a beginner, got the printer about two months back. I didn’t do any special tuning apart from auto leveling the bed.
I printed a temp tower with this filament, and it was okay from my viewpoint. Long overhangs were droopy on lower temperatures, and it had stringing from pointy ends on higher temps. I printed a few PETG prints before, but nothing with such fine details as this hexagonal thing.
Can you point me to some good source of info about tuning? For a noob like me it is hard to tell good resource from slop-compiled one…

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.

Thanks for another interesting point. It is faster than you are suggesting. My slicer settings for “external perimeters” is 25 mm/s and for “perimeters” is 40 mm/s. There are no other type of movements on these hexagonal structures.
I may try slower printing at some point, but it’s already a 7 hour print 😄

In the oven??? But wouldn’t it just melt? I have a gas oven, I don’t think it can go too low. But I will look it up. Maybe microwave is a way to go. Thanks for the tip.

That also makes sense. I imagine if there is a way to increase adhesion between layers that would help with such problem

2-3 weeks before I put it into a dry box with a bunch of silica gel
- Comment on Help! What is wrong? 1 week ago:
Thanks! I think I unpacked this filament about a month ago, and it was on open air for about two weeks, in 40-50% humidity. then I put it into a dry box with a box of silica gel, and it stays there at about 20% humidity. Until I take it out for a print. Is silica gel good enough for drying? I don’t have the drying machine.

I’m running one Pi-hole, but not on RPi. One is an LXC container on my Proxmox host, another is on dedicated Dell Wyse thin client box.
- Comment on Backups? (and Intro) 4 months ago:
It’s been my obsession for a while! It even starts to feel like a disorder sometimes as I’m struggling to find an ideal solution…
I ended up centralizing my most important data (family media files and personal documents) in Nextcloud. This data is backed up with Duplicacy - 1 copy to local NAS and another to Wasabi S3 bucket.
I also use Duplicacy to backup various Docker volumes of the stuff I run at home and my main PC home directory.
Apart from that, I use Time Machine for Macs with an SMB share on NAS. And Proxmox Backup Server backs up everything which is not in Docker to another NAS share. These backups are replicated with HyperBackup (Synology app) to Wasabi S3.
- Comment on localhosting: selfhosting to the min 5 months ago:
Not sure how many services can be hosted in that way and remain useful. But it’s an interesting idea overall! For myself, I could run a Git forge on local PC. Since I’m the only user, and I just keep my scripts there, it is fine not to run 24/7.
