Printing a case on a corner
I'm still trying to optimize the printing of my case and with the help of everyone, my understanding has improved greatly. This leads me to my next iteration which is trying to print the case from one of the corners. I made an initial attempt and as anyone can see, it didn't go so well. However, the bit that did print, it looked REALLY good.
I'm looking for input of the changes I would need to make in order to print it on one of the corners. The information I've gathered thus far, I would need to maybe create a 45-degree angle to get it on the bed to try and get it to "stick". Then I would need to add supports from the bed to keep the part stable. I'd probably also have to had internal supports to keep everything where it needs to be inside the case. Am I on the correct path?
Any ideas would be greatly appreciated.
Kindest regards.

I mean, is that an intellectual exercise or are you trying to actually print it? Both parts should print perfectly fine on their back, with just one paint-on support in the pocket of the base. In the attached 3mf I used organic supports but in reality I would probably use snug.
Can you put it on its corner? Sure. But why? Life's too short.

I just realized that a) the pocket is in the top, not the base, and b) there was a paint-on support in the original that I didn't notice.
Here's the revised 3mf

Thanks FoxRun3D! I can print them flat but I keep running into odd issues, the base part, always has some kind of band sticking out about a 3rd of the way up from the flat surface. Then, there is always a "notch" that occurs up from the base plate. It's very strange, it's like the gcode is telling the machine to move, and it physically does to create the offset. I also tried printing more than one at a time, in this case only 2 will fit on the build plate and I can't get them to print without them lifting off the plate and ruining the print. This is much more difficult than I ever imagined, LOL.
I was just reading about how to "correctly" print cases and one of the "best" ways is to put it on a corner. I was just seeing if that was an option to get a more consistent print while printing more than one at a time.
Thanks again for taking the time to look at all my craziness.
Kindest regards.

You're probably witnessing the infamous bulge, a well-known phenomenon, with dozens and dozens of pages of discussion in this forum.
There are several threads you might want to look through. TL;DR: Many suggestions, no universally applicable solution.

Also, Prusa wrote an article on it: https://help.prusa3d.com/article/the-benchy-hull-line_124745 but also highlighted that their specific solution is not universally applicable.

RE: Printing a case on a corner
Going through the links, I solved my "bulge" issue by slowing down the Perimeters down to 60 mm/s from 80 mm/s. Only thing left is this anomaly I have on the base piece. It's creating an outward "notch". There's nothing I can see in the slicer that is explicitly telling it to move when printing. The machine is physically following the path to create that artifact. I have no idea what is causing it.
Thanks again for your assistance!
Kindest regards

Hard to tell from the photo but I suspect it's a seam, from looking at the slicer preview. When you slice and go to the preview, click on the seam button.
With the round corners, the slicer can't hide the seam in one of the edges. You can play with the seam placement options or use paint-on seams to put the seam somewhere least present.

RE: Printing a case on a corner
That's AMAZING! I would have never gotten there. When I click on the Seam, sure enough, shows up in white, gah. Now I just need to figure out where to "hide" it.
Thank you again so much!
Kindest regards

That's the downside of "all round" designs. Look nice but sometimes a challenge to find a good seams placement.

RE: Printing a case on a corner
I watched a lot of YouTube videos before trying my hand at 3D printing and real life doesn't reflect YouTube, LOL. I certainly have learned a lot from my little case, guess I should have started with something a little simpler, if that's even a thing, LOL.
Thank you so much for your patience and help figuring this all out!
Kindest regards.
