The union between the two pieces that make up this design is made with a 9mm shaft to allow the shaft to rotate and make it more comfortable when exercising. The attachment to the bottle cap is made with two screws at the bottom of the grip, which already has the holes marked to insert them. Holder to install in a water bottle to do exercise. You can join both parts of the design with a 9mm rod in order to allow the turn of the hand holder, so it is more comfortable while practising exercise. To fix the holder to the cap, you can use two screws. The piece has two holes on the bottom to make easier this step.
