An idea for these poles, if they could be made 100% modular by having a design for each material, but not a single set in stone pattern. Instead of only being wood and stone, it could be wood and copper. So not only is it modular in parts, it’s modular in colours as well.
My idea was another machine to deal with these modular parts, where you select the base material, then the trim/filigree, and then need to put enough of each in to make one.
It could get a little tedious, but I think it’d be worth it to have 100% modular items like that. (Obviously not applicable to every item, only certain decorations was my idea)
