Subject: coffee pot lid 

I have recommissioned the Zojirushi coffee pot lid. You may, once again, align the dots in order to make the carafe pourable.

Details:

The Zojirushi lid is a two part mechanism:

  1. The top part of the lid must be removed for cleaning.
  2. When replacing the lid the two components must be aligned to < 3 mrad precision so that the "teeth" are able to land in the groove.
  3. There is a 4-fold degeneracy in this process. To break the degeneracy, align the dot on top with the spout gap (visible from the bottom view).
  4. After proper alignment and mating, the two parts should snap together and the relative alignment wiggle available should be < 2 mrad.
  5. After screwing the two-piece lid onto the carafe, ensure that the 2 dots are separated by < 170 deg in the closed position.
