Jo's new sink knobs

thingiverse

My client, who struggles with arthritis in both hands, requires specialized easy-grip tap knobs that can be easily turned without straining her joints. The standard rounded knobs on her new sink were a major obstacle, making it impossible for her to adjust the water temperature or pressure. To address this issue, I designed a simple solution: slip-on knob covers that fit seamlessly over the existing taps and are secured in place with an M3 grub screw.
