3 Cube Calibration

3 different sized cubes for calibration. As files indicate. Yes, there are lots of calibration cubes with the same information showing below. It's not hard to design and make cubes and I made them and placed them here primarily for my own convenience.

if:
e= expected dimension
o = observed dimension
s = current number of steps per mm

then:

(e/o) x s = your new number of steps per mm

e will always be the value of the size of cube you are calibrating against.
o will always be t
