Spiral Vase mode.
Bottom Shell Layers 5-10. Brim 15.
If you're having trouble printing in vase mode, try using a 0.6mm or 0.8mm nozzle. A larger nozzle improves layer bonding and overall print strength. Alternatively, you can turn vase mode off, 2 walls, no infill, and no top or bottom layers.
Can scale to any size.
