A notice. You may not use a mix of the set screw hole's center over the base shape. See knob_base(). Rotate([0, 0, i * (360/Knurls)] rotate([0, TaperAngle, 0]) rotate([0, 0, 90 + cone_indents_offset_angle + ((360 / sphere_indents_count) * z)] sphere(r = sphere_indents_radius, $fn = sphere_indents_faces); height = 266 + tolerance; rotate_vector_cos = 0.94; // 'x' of 20 degree rotation rotate_vector_sin = 0.34; // 'y' of rotation left_edge = -rotate_vector_sin * rail_depth; right_edge .
