Bottle cap remover tool

At eighty I do not have the hand strength to remove some of the plastic bottle caps. I downloaded a file for the smaller soda bottles and printed one. But I also drink "Gatorade" which have a larger cap. I drew a 2-D in Inkscape and used 123DDesign to extrude it out.
This one will fit many of the "Gatorade" bottles but they for some reason have a slightly larger one that they also distribute. I am including the DXF file if you want to change the size of the section where it contacts the bottle cap. have fun
The smaller one is from Thingverse
