I know there are some other models out there. I wanted to have a simple and easy to use calibration for flow with .6 and .4 nozzles. I attached some brim around the corners for better bed adhesion.
Please keep in mind
FlowCube_3_walls_p6 – for nozzle size 0.6mm
FlowCube_3_walls_p4 - for nozzle size 0.4mm
Flow is not the ultimate solution. Calibrate your extruder, temperature and retract settings. I would then continue with flow calibration if needed.
