Thanks a lot for uploading the mega model!
The model looks good besides the holes. I also noticed the part names you added. The shortcut to make cross sections is actually really nice, I'll definitely note it down for future use. Your model has made me hungry for even more detail. I think I will try and look into importing the model using the script myself and see how far I can get. One alternative would be to ask the Japanese creators if they have a full model which they can share. I'll look into that. Let's see how deep the rabbit hole goes..
