We all know that 3D printed items are not “food safe”, but I don't think a few microcavities in PLA will turn your salt and pepper into biohazards. But I'm neither food scientist nor lawyer, so decide for yourself.
Prusaslicer asked for brims and supports, but I printed without them, no problem. The included 3mf file for Mk4 input shaper prints at 0.10 mm with variable layer height, helping to smooth out the sloped top surface of the shakers.
Thanks for your likes and makes. Check out my collection “The British Museum” for other historical artifacts that are transformed into useful household items, or just art.

The author remixed this model.
The STLs are created from the downloaded OBJ file, then cleaned up in MeshLab, and processed in OpenSCAD to hollow the interior, add the base with threaded access hole, and shaker holes.
