I just got the new Ender 3 V3 SE, and out of the box the auto bed leveling on my printer did not completely work properly so I whipped up this file for manually setting the values. To use, just run the auto bed leveling to get a start point, and then print this file and use the results to manually set each calibration point on the printer. 

It is a set of 4x4 20mm squares, 0.2mm tall. Designed to be printed at 0.2mm layer height.
