  • Ha, thank you. The themeing is not at all my complaint with these tools, but I appreciate the tip! I look forward to seeing what freecad produces, it has a lot of potential but alas, not a lot of funding to make sure the devs can afford to eat.

    Well, then we need to keep donating to keep bread on their tables! :) I have no prior experience with any CAD-tools, so I guess I won’t notice the shortfalls of FreeCAD UX in the same way as other people who have more extensive experience with CAD in general and other tools specifically. I also don’t have very demanding needs of functionality, as most of what I draw are fairly simple structures for FDM-printing, and FreeCAD has been excellent for that. I would love for FreeCAD to get the point of being viable in a professional setting - do you know of any good write-ups that details what is still missing for FreeCAD to fill that space?

    Last I played around with them the blender cad plugins all use poly modeling, which puts them out of the running for anything more complex than FDM parts. Primarily they exist to either support 3D printing or for simulation/animation of simplified parts. They’re… better than nothing, for sure, but unless you need something specifically given by blender you’d be much better served by just using freecad.

    Alright, I thought perhaps they were designed to give an alternative workflow to drawing in CAD for people who are more familiar with or simply prefer Blender. I have tried to make some parts in vanilla Blender, and control of dimensions is horrid, but otherwise I do prefer to work with geometry in Blender over a CAD-workflow. But I can see that if you are doing serious CAD-work, that’s not going to cut it.








  • ETA: Well, I toured the Calibre-Web settings again, and now I can upload books and covers. Must have been a little tired on my first attempt. Still couldn’t get the conversion to work properly - I only have the option of going from EPUB -> KEPUB (whatever that is). I typically prefer reading PDF on my current reader, and I have users who need .azw3 for their jailbroken Kindle device. I guess the paths to the conversion tools aren’t properly configured.

    ETA2: Now I got the conversion to work as well. Seems like I will be able to use it with Calibre-Web only as well. Nice!

    Hm, I’m using lscr.io/linuxserver/calibre-web:latest, which is version 0.6.26 (5a1f3d8eec42d03228b1e5dec9bc750ca10bbc94 - 2026-02-06T20:40:07+01:00). Looked again to see if I could find a way to do it, but no.

    How do you upload books directly using Calibre-Web? And do you not have Calibre running behind at all, just the original database?

    An other shortcoming of Calibre-Web seems to be that I am unable to convert books from the UI (that is thankfully very easy to do in Calibre). I added some Docker mods that I thought would allow me to do this, but I have at least not found a way.

    Nice to know it works with Kobo - I don’t have one, but if my current reader stops working I am likely to get one of those.







  • otherwise they will be prone to warp and collapse in on each other. If your item will be as tall as you suggest, this is likely to happen before the print even finishes

    Yeah, this is what happened in the original, failed print.

    I ended up making the model with 3mm thick walls, using two perimeters and 10% adaptive cubic infill (I sliced with gyroid as well, but it looked weird). Turned out great. I made some that were not quite as tall as well, with 2mm thick walls and 3 perimeters, which worked fine as well. It might have worked for the main boss here as well, but I’m not quite sure. The difference between the models was about 55 mm in height. The difference in material usage between the two options was negligible (< 10 g), with the infill variant coming out slightly lower in consumption.


  • Good lord no. Don’t do that. That would be a waste of filament and also cause a host of other problems for you.

    Just to be clear, it is the “hoping to use infill to get some support” that your response is aimed at, right? Out of curiosity, what kind of problems could I be looking at for this?

    In the meantime, I’ve been printing some smaller bins of about half the height of my problem where I increased the wall thickness of the model from the default 0.95 mm to 2 mm, and used 3 perimeters, which resulted in fairly sturdy walls.

    Looking at the same bin with 2 mm walls without infill, and 3 mm walls with infill, there is barely any difference in material usage.


  • I was writing up some additional questions as I didn’t quite get your suggestion, but while writing the response I think I understand. You suggest that I increase wall thickness in the slicer settings to match the model thickness, and not only in the model?

    I was hoping to use infill to get some support between the outer walls and avoid having to use too much plastic and not having a single, free-standing wall.

    If I understood you correctly, do you have a suggestion to what a suitable wall thickness would be to avoid the issue I described?
