(360/Knurls)] rotate([0, TaperAngle, 0]) rotate([0, 0, 90 + sphere_indents_offset_angle + ((360 / cone_indents_count) * z)] sphere(r = sphere_indents_radius, $fn = top_rounding_faces square(top_rounding_radius + pad, top_rounding_radius + pad); rotate_extrude(convexity = 5, $fn = knob_faces); // @todo Refactor the scaling algorithm and parameters to be tuned further. Licence You can even use a mix of the main (cylindrical or conical) shape.
