Destroyed Apartment

thingiverse

I'd be happy to help you out, though - a bombed-out 3-story apartment is still a pretty decent project. This model will likely be quite messy when it comes to printing, but hey, that's kind of the point: you want the building to look like it's been ravaged by war. Go ahead and give it a print and see what kind of mess you end up with after trimming. You might also consider splitting the model into separate floors using 3D Maker to make the vertical printing process easier.
