A small printing-test to check the presicion of your printer.
& torture-test for those who have problems with non-sticking or lifting prints.
Base measures: 40mm x 60mm x 1mm
(In my case I found out that the X,Y,Z measurement are all correct, BUT the holes did not have the right dimensions. Still trying to find out how to fix this)
Cura standrad "fine" settings with 0.2 layer hight and "Z hop when retracted" deactivated.
