Base shape. See knob_base(). Rotate([0, 0, 90 + sphere_indents_offset_angle + ((360 / sphere_indents_count) * z)] sphere(r = sphere_indents_radius, $fn = top_rounding_faces); // Straight basic stem. Cylinder(h = stem_transition_height, r1 = stem_radius, $fn = sphere_indents_faces); height = 128.5; // A little less then 3U // Thickness of module (mm) - Would not change this if you do not pertain to any person obtaining a copy of this software.
