This is technically a slicer torture test not a printing torture test. I had to come up with it to identify issues with my slicer settings when certain pieces of the object simply do not get rendered by the slicer.
In this particular torture test the thin walls are 0.4mm thick. Slicers often make walls disappear here and there. See screenshot. Most of the time it is OK. But sometimes one may need the slicer to slice precisely. This is when this thing helps.
