bathtub rubber strap

thingiverse

I am trying to grasp a simple notion here - rubber straps designed to hold bathtubs in place during transportation. What I need is something more practical than what these current straps have to offer. These should ideally fit onto every shape of tub, be incredibly durable and strong, so that even the heaviest ones can be carried without slipping out or breaking off during shipping. Is this too much to ask?
