3D PRINT SETTINGS:
You can scale this model up and down to any size you want.
It comes as a solid model, and you can turn it into a vase by either:

• using vase mode (also called spiral vase in some slicers)
• or use regular print mode but set the top face layers to 0 and infill to 0%.

For vase mode, you can use any nozzle size, with roughly the following settings:

For a 0.8mm nozzle:
• activate "vase mode" (spiral vase or spiralize)
• Layer height: 0.3 mm/layer
• Line width: 1mm

For a 0.4mm nozzle:
• activate "vase mode" (spiral vase or spiralize)
• Layer height: 0.2mm/layer
• Line width: 1mm

I printed mine with 0.8mm nozzle and added some fuzzy skin:

• fuzzy point distance: 0.4mm
• fuzzy skin thickness: 0.3mm
