Inspired by the great work of @JoshK and his simple 4-cube form file, here’s 9-cube version complete with graduated markers and an indicator on top to remind you which corner of the build platform each cube came from. So you can pop them off and stick them in the wash without confusing yourself.
I used these to zero in on accurate Z-compression correction figures for different areas of my build platform during a sensitive print-on-base project.
