Draw an exploded assembly diagram of a manual coffee grinder, as an SVG. Use a hand grinder with conical burrs rather than flat burrs.Frozen at v1. This model got this and nothing else.
Top to bottom: handle knob, crank, body, outer burr, inner burr, spring if drawn, adjustment dial, catch jar. The drive shaft runs through the body and both burrs, so it is left out of the order, the way the French press leaves out its rod. The adjustment is at the bottom, below the burrs, and the inner cone comes out downwards through the fixed outer ring. Checked against Comandante's FAQ for the C40, Coffeegeek on the Timemore C2, Hario's spare-parts list and a review for the Skerton Pro, and a guide to the Porlex Mini. The Skerton has no spring, so the spring is not required. How it is scored, and this run's files on GitHub.
