Mortar & Pestle Dry Grinding Tool

thingiverse

Needed a tool to crush dry cat treats into powder to mix with my cat's meds, but wasn't satisfied with existing options, so I created my own. I designed the pestle and mortar in PLA since I'm only doing dry grinding, while PETG would be a better choice if you'll be working with moisture and are concerned about food safety. To achieve a smooth finish, I printed at 0.16mm resolution, 220°C temperature, and 75mm/s speed. For added durability, I recommend using at least 50% infill and boosting the top layer thickness to 2mm. After printing, all that's needed is a quick sanding of the bed-facing end of the pestle to remove any sharp edges and make it more comfortable to use. I've provided STL files for both individual items and the set as a whole. The example was printed in Eryone Marble PLA.
