It's challenging to tell from the photos enough information to answer your questions. My largest printer capacity is 250 x 300 base, 250 high, but the key aspect of printing something like this would be orientation during the print. One wishes to have the orientation such as to avoid the requirement of supports while printing, but also to have the orientation of the layer lines for maximum strength. Would you consider to attach the STL files which comprise your work and perhaps to include the un-segmented model as well? I don't think the un-segmented model is best suited, regardless of print capacity, but it would be more helpful to determine best strength orientation of the layer lines. If you are in the USA, consider also that I would be willing to print the model, if it proves practical. I'm certain I'll be less costly than a service! It's a hobby for me, not a source of income.
