If made of metal: For best results DON'T keep it carefully pristine?
Or regardless of materials: CONSIDER adding in some small scratches and dings to the version of the file you will print (keep a copy of the pristine version of the file you showed us of course!).
Rock tumbler with NO sand, but rocks of carefulky selected hardness and short run times at least at first?
Maybe grime it up?
My best guess at how to do that: apply (hot?) dark crayons they rub most of it off eith paper towels (NOT a more professional buffing cloth, since that might take too much crayon off).
... Or just rub with dirst from back yard??
