Depth Track rings

SummaryDesigned for https://www.thingiverse.com/thing:2559731/fileseach ring should slide smoothly onto each pin and the rings are thin enough that 2 rings can potentially fit onto one pin.Pro-tip: when printing the tracker... Put the tracker on, angle it, and print it so the face of the tracer is printed level.That way, the face is nice and smooth, and the pins are perfect. add ironing for an extra touch.
