Short description of error
Export STL scaling / World scaling relation broken
Exact steps for others to reproduce the error
Until now, I've changed the World scaling to 0.001 and metric for constructing of printable objects, which always gave correct results, when exported via the 3D Print Toolbox! No matter which slicer I used afterwards. In the viewport it showed the correct size in mm or cm, and in this size it was being exported. If I do the same now, the exported stl is to small by the factor 1000 (the exact reverse of the scaling setting), which results in very tiny objects.... If I change the scaling to 1, the export is in the right size, but the object is suddenly 200m big in blender instead of 20cm... And I can't get it back to that it shows the correct dimensions in both cases.
