How to make a donut ? November 03, 2013 10:49AM |

I would like to be able to make a donut-shape.
So in fact a ring that is a circle 90 degrees on its perimeter.
Should I repeat a sphere around a circle to get there, or is there a better formula ?

//from my library
module torus2(r1, r2)
{
rotate_extrude() translate([r1,0,0]) circle(r2);
}
module oval_torus(inner_radius, thickness=[0, 0])
{
rotate_extrude() translate([inner_radius+thickness[0]/2,0,0]) ellipse(width=thickness[0], height=thickness[1]);
}
torus2(80,20);
