I’m trying to find a scale model of…a giant tree, but not just any giant tree.

Ideally I’d like something similar to the Force tree from Last Jedi, but only insofar as I need it to have multiple trunks and an interior space—preferably as large as possible.

Even more ideally, I’d like to find this as a physical model—or lacking that, something that I could print (no doubt laboriously) on a 3D printer. I’ve googled around and can’t find anything remotely like what I’m looking for. Is there anything like this out there?
