This 20 x 20 x 20 mm calibration cube will help you with printer tuning.
I also added an upwart pointing arrow and a 3DBenchy-style first-layer-squashing test on the bottom of the print.
Printing Recommendations: 0.2 mm layer hight, no supports needed,
15 % infill, 3 perimeters.
Tipp: Optionally, to further calibrate your 3D printer, just print this cali cube and you can then measure this models dimensions against the expected dimensions as a starting point for e-step/flow calibration.
This is by purpose a quick test.
For a more comprehensive test you might want to print the All-In-One 3D-Test instead.
Hope you enjoy using this model.
Happy printing!
