Hot water bottle opener

My wife and my mother had been using various other tools to help open hot water bottles and to tighten them as they can get pretty tight at times, so I designed and printed a tool to make this easier. They both love it!

I guess it would also be useful for people who can't grip the lids easily due to arthritis and similar conditions.

It doesn't need any supports. I printed it in PETG with 20% infill.
