This another Vase generator made in OpenSCAD.
This one creates low-poly vases with optional spikes.
I encourage you to play with the customizer or download and tweak the OpenSCAD file and find your nicest vase.
Also included a ZIP file with 50 STL's ready to print

Tips: Increase flow, reduce speed and use 3 or 4 bottoms.
Another tip: If you have a small nozzle (0.3 or 0.4mms) can increase the 'wall width' to 0.5 or 0.6 to get a stronger surface
