Z-seam Optimization ringing / ghosting

***What***
A way to reduce ringing by adding a small groove to a model and aligning the Z-seam to it.

***How***
-Load the STL file into a slicer (I used Cura)
-Make sure walls are printed counter clockwise (default in Cura).
-Align the seam to the groove, Cura instructions below:
Set the Z-seam settings to "User specified"
Check "Z-seam relative"
Set Z-seam Y to -1 or any value that is within the diameter of the model. A value outside the diamater also works but will not be quite as go
