Parametric OpenSCAD remix of Campbell Planter

This is a parametric version of the Campbell planter. I wanted to put it on a glass jar, so the usual scaling procedure to resize didn't work for me. I decided to redraw the whole thing in openscad and make it parametric, so it's pretty easy to change dimensions and export to stl, hope someone other than me finds it useful someday!

(note: see Campbell planter for more info on how to print/use)
