Polar vase

I thought this would be a nice way to demonstrate polar graphs to my kids. Desmos makes graphing polar coordinates ridiculously easy. Add a variable that creates a nice 3d printable transition

Make a nice graph. Then add a variable (ie 'j' or 'k') that creates a nice 3d printable transition.
Copy this as a new function in the openscad file:

function newpolarfunction(z,t) = let(tt = z % 2 == 0 ? ttstep : (t+shift)tstep, j = z/zmax - , k= , rr = ) ) [rrcos(tt),rrsin(tt),z*zstep]; Comment out the current function at line 106 and add the "newpolarfunction(z,t)"
