About this 3D model

After lots of tests, I ended up with this design.It's just another "Bottle Cap Opener". but: Higher to accept different caps diameter.Big enough to help unscrew caps but not too much. (Let's save filament).Ergonomic Design to fit Thumb-Index grip.Large top hole to let expel caps.Little hole to tie it up to something and never loses it."Direction of Usage" top sign to help those who just can’t get into it.
