Thanks! I’m saving that link, and I’ve also saved your list of when you change patterns for future reference.

That’s a nice service, thanks for the share! However, I couldn’t quickly get an overview of what metadata may be included in a .3mf file, so I won’t upload it for now. Thanks for the offer to look at the file though. :)

Gyroid infill used to be the default in PrusaSlicer, but they changed it to grid when the MK4 came out with input shaping and much higher speeds. Straight lines gain most from the increased acceleration. Gyroid will now make your printer vibrate like crazy.
Good to know - don’t think my neighbors would be all to pleased with additional noise (and not me either).
This is also not cubic infill, that’s another one (which I would recommend over grid for structural pieces). I actually almost always use Adaptive Cubic infill, which saves a lot of filament.
Ah nice, it seems that the adaptive cubic will make larger pockets? Neither cubic nor adaptive cubic seems very… cubic to me, though. Why is it called this?
So far I’ve not been making any structural pieces, but that is something I will remember for when I do.
I also believe that your print would probably had turned out fine in the end, it doesn’t seem like there were any catastrophic failures in your photos, despite the noise.
Hm, OK, maybe - I think however it would have been difficult for me to keep it going when it sounds like I am destroying the printer for every layer

Is there a good way to set it up with a remote?

It’s how I have been running it for the last two years now. Coupled with Jellyfin, it is such a better experience. My mother just got a new TV - I think I will set up something similar for her.

Thanks for a very thorough answer!
It’s possible your original Blender design had an issue. Blender is not always kind to 3D printers.
I’ve had good success with previous Blender files, although this is the first time I’ve used a boolean operator to cut out anything. I usually use FreeCAD for these custom Gridfinity pieces, but the process of converting the .stl mesh to a solid part in FreeCAD seems a bit error prone (several steps involved), and I haven’t yet used booleans in FreeCAD. I could try that again.
The first thing I would tell you is to stop using cubic infill, it is evil. It never always causes me failed prints, especially larger prints. Nozzles often tend to drag across the previous layers and can easily cause failed prints. I can even hear the nozzle hitting the infill as I print. I often recommend gyroid as a good all around infill pattern.
Good to know! I use PrusaSlicer, and this grid infill is the default. The way you describe it sounds like what I experience, and I can in fact see some artifacts when I inspect it closely. Though, the sounds I hear would only start when the concave part starts, and that’s also where I see the failures. But that could possibly because there’s too much overhang over the cubic infill? Anyway, I checked out gyroid pattern, and it was pretty dense with the 15% default infill value. What type of infill % do you typically use? Seems I could get away with less here.
I look at it and I wonder, does the rolling pin need to be supported full length? A wooden rolling pin is ridged and only needs minimal support on the ends. So I might just design the cradle only at the very ends. And then design the middle to be a simple flat that connects the two end pieces. I might even skip the middle altogether and just print the ends. That saves the most material and time and still does the job perfectly.
You mean an open container with maximum depth and width between the ends that holds the ridges? That could be a good way. They way I ended up doing it was essentially just a rectangular cut-out which worked fine and is similar to your suggestion (although I could save more material doing it your way), but feels less custom… as if that is a goal in itself. I would not like the gap by just printing the ends though, as I wouldn’t be able to squeeze anything else underneath and it would not look right to me. Wish I didn’t think like that, so I could save material, but I know myself enough that I would be annoyed every time I opened the drawer…
When it comes to slicing your print, orientation matters. How you support overhangs can be tricky and often compromises must be made. While I will use the auto supports as often as I can, sometimes you just need to use paint on supports to get what you needwhere you need it. Pay attention to the top zed support gap. The defaults are never right. I always open them up more. With a .40mm nozzle, I use a .265mm gap. For a .60mm nozzle, a .365mm gap. You might even need to print your parts at an angle. Often tipping the part at 30 to 45 degree angle can make those nasty over hangs completely printable without supports. And this is only a good beginning. How fast you might print an overhang matters, the amount of cooling fan can affect the over hang, lots of fine details that you will learn about as you keep doing this.
This I will need to read up on more. I don’t actually use supports for these Gridfinity prints (but PrusaSlicer does warn me about potential instability…). The printer handles the overhang between the grids fairly well, but I guess I didn’t think about the long lines crossing the infill. In other prints I’ve only used the auto supports. Could I ask you what slicer you use?
Good Luck and never fear making a mistake!
Thanks! I must admit I do fear it sometimes when the printer makes some weird noises…

You can export your data from Spotify, and use that as a basis for downloading songs via for example yt-dlp (this can be automated), or slowly build it up again over time in whatever system you set up by buying the albums/compilations containing the songs.

I find the non-fiction stuff he writes good (e.g. The Internet Con, Chokepoint Capitalism). I believe this book is like that?
I found his fiction, based on the one book (The Lost Cause) I read, to be a bit juvenile in style (as in feels like a young adults kind of book) to the point I didn’t quite enjoy it, although the topics are interesting enough.

What does Jellyfin have to do with that? If you implement acess control in the reverse proxy, requests from non-whitelisted IPs are just not forwarded to Jellyfin.

- Comment on Round Two: Can I manage to set up Jellyfin correctly this time? 5 weeks ago:
I use Nginx Proxy Manager and whitelist my remote users. They all have static IPs though, so its a workable solution for me.
Before I used a whitelist I would go through the access logs, and could never find any attempts to exploit the endpoints - only some random bots trying to find some admin page assuming it was another service. Not saying you shouldn’t take it seriously, but you are likely not subject to these attacks the moment you expose it.
That said, there is a discussion about these endpoints on their repo. At some point they will be fixed (my impression is that they are hampered by legacy Emby code). When they do, you could do this more securely.
- Comment on Why Americans Can’t Buy the World’s Best Electric Car 2 months ago:
I’d think enrollment rates would be a severe lagging indicator of education quality. Institutions could likely coast on reputation for quite some time after education quality tanks. Inertia is powerful, and some could even knowingly decide to go to poor educational institutions just for the status it still gives among peers and in their community.
That said, I have no first hand experience with US higher education, and wouldn’t know what the quality really is, just saying that enrollment rates probably aren’t a great indicator of it.

- Comment on Your household smart products must respect your privacy – including your air fryer 2 months ago:
I bought a kettle with some WiFi features, but never planned to put it on my network as it works without it. Or was supposed to, at least. The thermostat was erratic and it needed a firmware update to fix it, only installable via this WiFi-connection. I set up a temporary VLAN just for the update, and disabled the VLAN right after. Then I took a shower.
I find it odd that one of its core features worked so poorly out of the box. And it’s not like it was a way to trick me into connecting it either, as I first got a replacement part because they didn’t know what the issue was.

And it has an Android fork (FreeTube Android), and can have playlists, subscriptions etc. synced across devices with Syncthing. It does sometimes result in sync conflicts though, but if you reload it before using it on a device, you will be fine. Most sync conflicts I get are for history, and that’s fine by me to lose some history.

I use it consistently with few issues. Once in a while, usually on Thursdays (when it seems YT rolls out changes), something breaks, but the devs are quick to fix it. The last issue I experienced was when YT transitioned to SABR, and it was out for a day or two before they had things working again. I am at least perfectly capable of going without for a day once every two months.
It’s also one of the projects I’ve used to learn more about how fixes are worked on in FOSS. I will typically run nightly builds also - I find it pretty cool to follow an issue and once they push a fix I can instantly grab that fresh build without waiting for it to be packaged.
