About this 3D model

This is the evil copy machine that we all love to hate. Ours must have a built mood sensor since it always knows when I am a hurry, because that's when it always does one of the following: - shreds my originals - jams up beyond all possibility of repair - very nicely accordions an 8 1/2 by 11 down to 8 1/2 by 1 (how does it do that?) - is being used by some idiot copying the phone book, 100 copies of his kid's sports roster, etc I have included two .stl's, one with ears and one without ears for better printing.
