This is a flexible non-slip multipurpose grip for fishing gear. The opening on the back allows it to stretch, and the durable thickness of the TPU makes it very flexible and long lasting. The rugged low-poly texture makes gripping narrow, heavy or slippery gear easier. Can be printed in multiple sizes for many different applications such as fishing poles, boat hardware, beach carts, net poles, bucket handles, fiberglass anchor rods and many more. It is very easy to print with a .6mm nozzle and no supports. We used SainSmart TPU. Enjoy.
