+Increase **flow rate** by ×1.05‒1.1.
+
+BrickLayers works for walls, so do not use 100% infill but more wall lines (it's stronger anyway even without this scirpt).
+
+So to calibrate the flow rate more accurately, you can run the flow rate calibration and increase wall lines a lot. It's not perfect but it's a start.
