Double / Quadruple wall vase mode Parametric

After many trial and error, finally I can finish this double wall project to create vase / cup/ pencil holder even planter cause its parametric (with some adjustment to printed it well)
Using what I called pre-sliced technic we can guide slicer (here I use Orca, other slicer maybe behave different) to slice the design exactly like we want.
For the Included STL Im using 0,6mm pre-sliced line height to be slice on 0.3mm (or 0.2mm if you want) smoothly without missing layer. all layer double walled as on setting with top layer (2layer if sliced on 0.3mm) using max rib to close the top
Using the vase generator we can slice many type of vase, cup or pencil case or small storage (using 4side) and spinning (or not) the layer smoothly.
Caution: default parameter is using non pre-sliced technic (0.12mm line height) to speedup OpenSCAD preview render. you need to change it from 0.2mm to activated pre-sliced feature and after waiting the preview render it will display different look. Need nightly
