For square, hexagonal etc. Shafts. ≥30 means "round, using current quality setting". Shafthole_faces = 20; // How much to cut off to create cutouts around the knob? Knurled = 1; // actually.. I don't know what this does. Pad = 0.2; // Padding to maintain manifold render(convexity = 5 square(top_rounding_radius + pad, top_rounding_radius + pad); circle(r = top_rounding_radius, $fn = top_rounding_faces); // Straight basic stem. Cylinder(h = stem_transition_height, r1 = stem_radius, $fn = 3, center = false); z_position = height - v_margin*2 - title_font_size; working_increment = working_height / (8+tolerance/3); // generally-useful spacing amount for vertical columns of stuff left_panel_width = 40; // [1:1:84] working_increment = working_height / 5; row_1 = v_margin+12; Initial stab at a charge no more than the cost of.
