Dog Tags for Infill

thingiverse

You can easily choose your infill density for various prints with these custom tags at hand. Each unique label features a numerical code discreetly engraved on its underside, except for the blank one. Print the specific tags you need by setting the infill percentage to their respective numbers and then link them together via a sturdy chain or string – I plan to use a PLA loop that's fused securely at both ends.
