Dead Rat Doorstop.

At last, a purpose for a deceased rodent. As a doorstop. It should function with most doors, contingent upon the gap size. The thin end of the tail measures approximately 4mm in diameter. I printed mine at a .3mm layer height with three perimeters, ten percent infill and four top layers. I utilized support material during printing, however you might be able to print without it successfully. If it tends to slide across the floor, try attaching a strip of sandpaper to the bottom for improved traction.
