Improved Flow ratio Calibration v3

Here's improved flow calibration compared to Orca or Bambu Studio. This is the third iteration from the original models: Improved flow ratio (extrusion multiplier) calibration v1 by jimcorner - MakerWorld, Improved Flow Calibration v2 by jimcorner - MakerWorld. The goal is to make flow rate calibration as straightforward as possible with a repeatable and clear standard. UPDATE: Bambu Studio 2.1.1 has since added support for per object flow ratio setting, you can see it by enabling the developer mode. Download the 3MF file, then you can open it and print with Bambu Studio. (outdated: Please download the 3mf file and slice it yourself in Orca, the 3mf does not work with Bambu Studio bc it doesn't support per object flow ratio setting! As a result, the print profiles uploaded by other people here likely won't work.) Why I upload this:the default flow calibration is bad at determining which flow rate has the smoothest surface with the monotonic top infill pattern, especially fo
