Summary
This part has tabs and holes.
The center tab of the row of 5 is supposed to be exactly 9×3 mm in size. Same for the hole in this tab. The two tabs to the left and to the right are smaller and bigger with increments of 0.2mm. The holes to the left and to the right have increments of 0.1mm.
There are three extra tabs down on the build plate, all of them exactly 9×3 but in different orientations.
If you print two, try one of the 9x3mm tabs to fit in the holes. You will see if your printer generates holes too small or too big. If so, chances are that walls are also too thin or too fat.
In Cura the parameter to compensate for this is called ‘horizontal expansion’. A negative value is needed, if holes are too small.
This test assumes that scaling is already correct. E.g. a 100mm rod is 100mm long. Plus minus a few tenths of a mm.
If you only print one, you can easily break away one of the three outer tabs, or cut away one end.
