Print instructions

I printed it in vase mode with .3mm layer height. I left the first layer speed the same but doubled everything else. Extrusion width was increased to 0.6mm (needs testing). I had to go to my filament setting under cooling and change the "Cooling Thresholds, Slow down if layer print time is bellow: " to 5 sec.
