Calibration Squares
thingiverse
Just a simple remix of HobbyHoarder's calibration squares, broken down to print on a single axis at a time (mainly to test my 3-point leveling). Use your slicer to reposition the squares in line with your axis, then print just that specific test. Nothing fancy at all, but the source files I found initially printed 4 squares, which worked, but added a lot of unnecessary time and pieces if I only needed one axis.
