  1. Hi @johnse, Your 30mm cube example with numbers really helps clarify how Cura "sees" these settings - thanks! I'd be interested in any references which provide similarly analytical explanations of the various Cura terms/settings and how they relate to each other, especially with diagrams (apologies if I missed that in the documentation). Let me apply my specific case to your example - a 30 mm cube with a 10mm cube void in the center, with 1.5mm walls. Suppose my tubular passage through the cube is 1mm in diameter. What I want is to set the walls of that tube to be 1.5mm thick and the remaining (non-tube) part of the outer wall to be 3mm thick. The example I shared uses variable infill to achieve this...although, for that example the non-tube wall thickness is actually set to 0. Is there a better way to do it?
  2. I just found some new information that seems to agree with the example I shared. That gives me the confidence to proceed with the CAD work I need to do to prepare my actual model. I'd still like to hear about any other approaches, caveats, related settings, etc. If it's helpful, here are the references I found on this topic... I based my first attempt on this helpful video - I then played around with Cura to create the example I shared. I also went looking for related discussions and, at first, I didn't find anything of interest. Since posting this question, I found this valuable discussion with additional details - https://3dprinting.stackexchange.com/questions/6522/different-infill-in-the-same-part . That post actually links back to a discussion here -
  3. That sounds logical to me, but I still don't get how to then use Cura to produce the actual part I want. I have CAD models of both the cube and the tube. For the example I posted, I imported these as separate files into Cura so I could control their settings individually. Then, within Cura, I combined them using 'Merge Models'. That's the only way I know how to generate the model I posted and I want to know if there's a better way. I could certainly use my CAD software to combine the cube and tube into one part/file, and then import that into Cura. What I don't understand is how I would then tell Cura that I want 100% infill for the walls of the tube and 20% everywhere else within the volume of the surrounding cube.
  4. Hi, I'm just learning Cura and have a question about defining walls within the interior of a model. My naive approach was to do this with per-model infill settings, where one model in completely enclosed within the other and used to locally modify the infill density to 100%. This seems to work, but there are many switches and knobs available that I still don't know anything about - is there a better way? For example, the attached model is a simple cube with a tube curving through it...what's the best way to make the walls of the tube solid so as to form an interior passage? What settings are most relevant for this sort of thing? Note that I am not particularly concerned with the printability of this example. Right now, I'm just focused on learning how to use Cura itself. Thanks! UMS5_Cube.3mf
