ATTENTION: THIS DESIGN WILL NEVER WORK I designed this when I did not know anything about 3D printing. It is too fragile and will break easily. This salt shaker is fully 3D printable, can be scaled to any size, and prints in only 3 parts. Just fill the body with coarse salt, and the knurled surfaces inside will grind it down. Make sure to print the grinder with support. The model entitled "salt" is not printable. Just in time for the holidays, this should be a fun conversation piece.
