I think you can make it from just fondant with a little tylose. Role out a square piece and use for instance a glass covered with baking papier (so it does not stick) wrap the fondant around the glass, glue the ends and let it dry for a couple of days. Or you can you use cake, cut out circels and stack them on top of each other.
Hope I’m not too confusing, it’s a bit hard for me to explain in English :-)
