xyz cross step calibration 3-2-1

thingiverse

I created a calibration test for primarily x and y axis, as I sought a more precise stepper-calibration model than the conventional cube. The advantage over the traditional cube-test lies in: Lining up a caliper with supports becomes much easier in xyz directions. A longer model provides more exact measurements. The cross-shape design enables faster prints Challenges arise from high infill, which may cause shrinking problems; however, the unique shape of the cross significantly reduces this margin of error.
