About this 3D model

I recently started carbonating my own beverages, using these supplies: https://bitly.com/bundles/o_4d50esl77e/8.... and following these instructions: http://www.popsci.com/diy/article/2012-06/how-make-your-own-home-carbonation-system.I love carbonating my own beverages, but attaching the Carbonater to the ball-lock requires a Vulcan's grip. So I created the Soda Grip to make attaching a snap.This fits just about all soda bottles with the standard cap, including 16 ounce, 20 ounce, 24 ounce, 1 liter, and 2 liter.
