Print at 100% infill with a layer height of 0.08mm with a base layer of 0.16mm
Swap Instructions:
Black until layer #5 at 0.48mm
White until layer #13 at 1.12mm
Gray for the rest.
Note: I had a different gray under the black because I wasn't paying attention which is why the base layer is 0.16 but you don't need to switch until 0.48. It doesn't show in the final result, so you could probably chop the bottom 0.32mm off and just print 1x 0.16mm black layer instead.
