This spice grinder design is a school project from 2010. I wanted to develop new original design, where the shape is classically cylindrical, but I made it special by dividing it to a thin stripes of constant width. Most of them are made of the stainless steel and 4 of them are transparent, so you can see the content inside. The lowest stripe has a bit bigger radius to make the grinder stable. In the upper half there is a double stripe to make a place for a label.
Use of the grinder is really simple and intuitive - you can just remove the inner part of the cover, fill the grinder body with your favorite seasoning and grind it the way you are used to.
