Orca has an appimage I’ve been using that prints well over wifi. I’ve picked up FreeCAD to start learning, but I’m told the learning curve is ridiculous compared to F360 and other non-CAD modeling programs.
It’s been a while since I needed to do this, but Blender had some viewport quality settings I tweaked on an old laptop years ago to smooth things out (if you haven’t already tried). It might have been the anti-aliasing settings…



Did people really not read this as a joke…?
