Infill density sample cookies - Honeycomb

UPDATE: I am learning more about Slic3r; I realized that instead of stopping the print manually that I could set the top layer to 0.... and let the print finish with no top surface. So I shortened the cookie to 3.35mm, set top layer to 0 for a new set of files, labeled V2. Same end result with less work on your part.
Note, the G-Code files are set for printing PLA. I also added the updated STL file.

I made these honeycomb-infill density sample cookies as a visual printing aid for myself.
