Our son designed these as part of a high school group project on "Maus" by Art Spiegelman, a book on the Holocaust. They represent three bunkers (hideouts) in the book: a secret attic room, a secret place in the coal bin, a secret space in a boot pile.
Everything prints easily except the coal bunker, there is some support material stuck inside it that we couldn't reach, but it doesn't hinder the mouse hiding out in it...
He printed 3 mice, one for each bunker. The mice are just a scaled down version of our mouse in another post.
