I designed this to Calibrate any printer for stringing. The various distances and orientation will allow a quick way to test your printer for stringing so you can tune it out. I came up with it because I found that my printer when I got it not only had a bad stringing issue but it also had a directional stringing between close points. This will allow you to test all the way down to the 1mm distance.

Once you have figured out your retraction distance and speed these should just come out as solid rods with Zero stringing at all. Please share freely
