Z Axis Alignment tool for i3 Berlin

I was unable to accurately calibrate the X Axis perpendicular to the Y , so at the end I designed my own tool. This is actually a holder for a Dial test indicator that will snap fit to the X smooth rods . You may have to enlarge / shrink the design , because when I designed this my printer was still a bit uncalibrated. With this you can achieve a great degree of accuracy.
