This is for a pewter casting I'm making. You are meant to place this in a green sand mold, then remove the pring from the sand (leaving a cavity where the print was), placing a wooden handle with a channel down the center in the cavity, and then pouring the molten pewter in the mold, creating a blank stamp which can be engraved with the design of choice. The piece needs to be printed with the best print quality possible so the sand doesn't stick to any rough surfaces when the model is removed.
