Spacer for the zero point adjustment pin on the Timemore 078S to remove the coarse-end dial stop for improved usability with brew methods that require coarser grind settings (pour over, french press, etc.). I found this to be required to allow for grinding fine enough for espresso and coarse enough for pour over without having to move the zero point adjustment pin.
This takes advantage of the fact that the grind adjustment dial on the 078 threads in and out when twisted which means that by spacing out the zero point adjustment pin the right amount it will not contact the dial stop pin on the coarse end of the scale (18) while maintaining the stop at zero (0).
