Overhang Finder + Auto-Orient
Which Blender versions does it support?
Blender 4.2 or newer. It is tested on 4.2 LTS and 5.1.
Does it replace my slicer's supports?
No. It shows where supports will be needed and picks a good orientation; your slicer still generates the supports.
Can I undo the rotation?
Yes, Ctrl+Z. Auto-orient only changes the object's transform, not the mesh.
