I'm designing a full color model but probably some elements aren't applying some of the rules for that material, so I need advice. The model has 1 shell with 4 parts, each one shown with a different color for clarity. First, the green bar has a diameter of 3mm and a length around 11cm. Maybe this is very delicate or lacks structural strength? I could replace it by two holes of 1mm to pass a nylon thread through them. Second, the orange part is supported only by the blue one and a little by the gray base. Orange and blue parts are on perpendicular planes. In case of problem, I could widen the union zone. For the base union, a prolongation of the orange part is also possible. Third, another structural strength question, the union of the blue part with the base, now with an area of 8x10mm. If necessary I could increase it. And finally, how durable is full color material outdoors? Maybe the wax will get lost under the sun? The main texture will be black numbers and marks over white or a light color, so no problem as those marks remain.
