Z offset Test square 2

0.2mm layer single square border with measurements @ 180mmx180mm. I made this to verify z offset at the farther end of prints, specific to isolating exterior edge feathering. I took the original idea I have posted here: https://www.thingiverse.com/thing:6553685 and re-assessed my need.
