Hi. Based on some informal searches, myself and Avinash Baskaran have
created a new open-source tiny project for creating rounded objects.

https://github.com/PubInv/SCAD-fillet-tools

This is part of our non-profit,  Public Invention
https://pubinv.github.io/PubInv/  .

This is heart of the single file we have right now, but it seems to work
nicely.

module rcone(coneTopRadius, coneBottomRadius, h,topCurveRadius,
bottomCurveRadius) {

rct = coneTopRadius;
rcb = coneBottomRadius;

rcut = topCurveRadius;
rcub = bottomCurveRadius;

hull(){
    translate([0,0,(h/2 - rcut)])      
   rotate_extrude(convexity = 10)
    translate([rct-rcut, 0, 0])
   circle(r = rcut, $fn = 100);
    
     translate([0,0,-(h/2 - rcub)])      
   rotate_extrude(convexity = 10)
    translate([rcb-rcub, 0, 0])
   circle(r = rcub, $fn = 100);
}

}

module rcyl(r,h,rc) {
rcone(r,r,h,rc,rc);
}

You could improve it with center= the same way as cylinder() does.

Admin - email* me if you need anything, or if I've done something stupid...

Thanks --- I created an "issue" in GitHub for that.
