Layer Height: .2mm or lower
Perimeters: 2 or 3
Infill: 40%+ works well with 2 perimeters, 3 perimeters can be anything
Cooling should be cranked up as HIGH as possible
Print this SLOW. WAY slower than you probably think it needs to be. There must be sufficient time for the fan to completely cool the intense overhang at the bottom of the print. I printed at a whopping 10/mm a second, but you may be able to print faster if your printer has better cooling than mine. Be prepared to make some tweaks and restart the print; I recommend keeping a close eye on the first hour of the print.
I successfully printed this scaled down to 80%, but it can potentially be printed even smaller if printed slow enough. Larger shouldn't be an issue.
