20mm Calibration Cube with tiny marks

thingiverse

I found most of the calibration cubes available here to have such huge X, Y, Z markings, Usually I felt that will cause for inaccurate readings. specially since I use an "outside micrometer" and not a caliber, and hitting the dead center on the text, is just... not gonna work for me. so this one has small markings, offset to the top right, to give me lots of room to take my readings. I hope someone else that uses an outside micrometer finds this useful.
