Plastic Cap Wrench

thingiverse

This innovative wrench, designed for those with arthritis like my mother-in-law who struggle with plastic soda bottle caps, features unique opposed teeth that flex upon application. Upon turning the wrench, a set of three teeth grip the cap surface, simplifying the process of opening and closing bottles. The teeth design balances ease of pushing on while maintaining a strong hold. I'd appreciate feedback from users regarding its effectiveness. After printing, clean up any rough edges on the teeth for smooth operation. This wrench works efficiently from both sides - simply press it onto the cap, unscrew or screw the cap back on, and leave the wrench in place for future use.
