System Information
Operating system: Linux-5.15.0-67-generic-x86_64-with-glibc2.35 64 Bits
Graphics card: Mesa Intel(R) HD Graphics 520 (SKL GT2) Intel 4.6 (Core Profile) Mesa 22.2.5

Blender Version
Broken: version: 3.5.0, branch: blender-v3.5-release, commit date: 2023-03-29 02:56, hash: 1be25cfff18b
Worked: (newest version of Blender that worked as expected)

Short description of error
[I have my scenes setup to metric and in millimeters scaled to 0.01 All other versions of Blender worked flawlessly with exporting my models as an STL in the correct size and units. Since the automatic upgrade to version 3.5.0 PrusaSlicer and SuperSlicer give an error that my model is in inches and not millimeters. No matter what I change the units to in the scene properties the STL comes out the exact way each time, in inches.]

Exact steps for others to reproduce the error

[Please describe the exact steps needed to reproduce the issue: I add a mesh, cylinder, and set the size to 10mm radius 2mm depth. Export the model as a STL. Import the STL into PrusaSlicer and receive an error message about the model being in inches instead of millimeters]

Is it same as this? https://forum.prusa3d.com/forum/prusaslicer/saved-in-inches-warning/

I have used random online print service and it reports that object is 2 x 2 x 0.2 mm when exported with both versions. This is same as stl file provided, though I don't know if this was supposed to be good or bad one.

When I tick "Scene Units" box when exporting the service reports 0 x 0 x 0 mm in both cases...

I assume you tested this on same slicer version, is that correct? Would be good to know how exactly they determine whether to use mm or inches. Do you know if this information is public?
