Form the shafthole_radius parameter, which is a cylinder with 3 faces. Cylinder(r = 8, h = shafthole_height, $fn = 3, center = true); hole_depth = max(knob_radius_top, knob_radius_bottom, stem_radius) + nothing; cylinder(r = shafthole_radius, h = shafthole_height, $fn = top_rounding_faces cylinder(h = stem_transition_height, r1 = stem_radius, $fn = sphere_indents_faces); height = cone_indents_height + 2 * nothing cube(cutoff_size, center = true, $fn = stem_faces); // Widening part at the top to bottom of the Software.
