Top square(smoothing_radius+pad,smoothing_radius+pad); rotate_extrude(convexity=10, $fn = stem_faces); // Widening part at the top. Rotate([0, 0, 90 + cone_indents_offset_angle + ((360 / cone_indents_count) * z)] sphere(r = sphere_indents_radius, $fn = top_rounding_faces); // Straight basic stem. Cylinder(h = stem_transition_height, r1 = stem_radius, r2 = stem_transition_radius, $fn = smooth // outer pointy indicator // cube size of circle fragments in mm. .
