Backlash calibration

thingiverse

This calibration piece is used to determine the x,y backlash of your machine. To calculate it, measure the width, hole width, depth, and hole depth of printed item; then apply the formulas below: x-backlash = (width + hole width - 30) / 4 y-backlash = (depth + hole depth - 30) / 4 In theory, every incorrect print configuration should cancel itself out.
