HydroJug / Stanley Opener

Friend wanted a tool to help open her HydroJug, I took some measurements and designed this in SolidWorks.Another friend tested on a Stanley and it works, I did horizontal and vertical print testing and the only failure I had was with Vertical and PLA. I placed all test subjects in boiling water for 30 seconds, only PLA deformed I placed all test subject, except the failed PLA, in the top rack of my dishwasher. No noticeable change post dishwash.
