You can use cardboard tubes from plastic wrap and aluminum foil rolls! You will also need five M3x20 bolts and nuts. You can print one part with three openings and one with two or print the part with two openings three times. Generally you can use more tubes and plastic parts to make larger stands for more spools. Use your imagination! If you have different diameter tubes, don't hesitate to ask for models. Reduce, Reuse, Recycle!
