Gcode/model to make calibration lines easier to remove

I’d seen somebody talking in discord a while ago about having some custom start gcode that would basically print some zig-zag lines over top of the calibration lines at the start of every print after the flow calibration is completed. This would make them much easier to remove as one piece. It wouldn’t interfere with calibration since it would be printed after calibration was done but before the model started printing.

Does somebody have a link to something like this, or is anybody willing to share (maybe on the user mods forum)? I’m guessing I could just make a model in STL for this but I figured I’d see if anybody already had something handy. I couldn’t find it with searching…
