The file 'Watering Cup Easier Overhang 3D Printer Model' is (stl) file type, size is 77.2KB.
I had trouble getting my overhangs to look good even at a 0.2mm layer height so I traced the watering cup in blender and then chamfered the bottom instead of having it be curved.
I also added 0.4mm tolerance to the parts that connect to each other.
