After laying the model flat on either side, the slicer produces a non-planer surface which requires supports.
I've included a copy of the mesh file with which it exhibits this problem.
I ran it through three different slicers: PrusaSlicer 2.7.4; plus Cura 5.4.0 and ideaMaker 4.2.1.5320 and I can only get PrusaSlicer to show that strange behaviour.
