Functional TPU Tank Tread Benchy

Tank Benchy with single piece movable treads printed in TPU. Install one wheel on each axle, thread through the base slot, cap each axle with the other wheel, then stretch the treads around the outer wheels. Make sure your TPU is dry or it may tear when you stretch it into place. TPU isn't the perfect solution for this, but it's quick and I thought it was neat printing it as a circle and stretching it to fit. I should have printed the treads in a bright color as the gif doesn't pick it up well. It doesn't roll particularly well unless on something that provides some friction, but it is pretty fun to play with in your hands.
