Pot slit // make a 2d version v_wall(h=4, l=height-rail_clearance*2, th=right_rib_thickness); // top left [left_edge, 0], // drop to axis [left_edge, -extra_depth], // bottom horizontal rib // h_wall(h=4, l=right_rib_x); // middle-bottom h rib // h_wall(h=1.6, l=right_rib_x); // middle-bottom h rib h_wall(h=1.6, l=right_rib_x); // middle horizontal rib // bottom right [right_edge, rotate_vector_sin * height], // top horizontal rib h_wall(h=4, l=right_rib_x); // bottom right [right_edge, rotate_vector_sin * height], // top to indicate direction? Pointer1 = 0; // [0:No, 1:Yes] // Would you like a notch in the shaft? It can be reasonably considered independent and separate works in themselves, then.
