    Just found this video from back when we first started 3d printing. It is a 20x20x20 mm cube with 70% infill, 2 perimeters, and .3 layer height, in PLA plastic. There is a 10x10x10 cube cut from the middle. We had a friend run over it with his car, and this was after we were hitting it with a hammer to test it's strength. Pretty durable stuff.

    Hammer test likely would have shown more wear, a tire is meant to be able to go over objects it is rubber and deforms to some degree in order to not destroy the tire. Something like an iphone case (with a large hollow area) would have been a better test. thanks for sharing coby

    Mike, I don't know if you watched the video on a screen larger than your phone, but hammer marks are clearly evident on the sides of the cube. As Coby put it, "Tough stuff."
