What the harness did to this run. The 12-minute clock ended it before the model finished, so this is where it had got to when time ran out.
All eight partsdecided by looking · Pass if every listed part is drawn as a separate shape and each has a label naming it. A part only named in a label or a comment, with nothing drawn, fails it. The label must say what the part is, in any words: a name that only says where it sits ("top plate") or what it is made of, or a mention in another part's caption, does not count.pass
Stack orderdecided by a number, from the filepass
Parts fitdecided by looking · Pass if each listed pair of mating parts looks as if it would go together as stated: the right angle, nested inside, or sitting on top. One pair that plainly could not fails it.pass
One assembly axisdecided by looking · Pass if one line runs through the middle of every part on each listed axis, and every leader line leaves from the same side. One part pushed off its axis fails it.pass
Labels matchdecided by looking · Pass if following each leader line from its label ends on the part that label names. One label pointing at the wrong part, or at nothing, fails it.pass
There is no post about this one, since only some results need one, so the picture, the source and the scoring are here instead.

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.
