I designed this for my own use, I'm an C5 quadriplegic, so my hands and fingers are quite shittyshittybangbang, can't get grip of anythin heavy or slippery. This can be used to lift lid with your thumb. When printed with PLA, or PETG, you can´t leave the tool on the knob.
In Finland you can buy this pre printed from HJ Visions, (contact:[email protected]).
Lid knob max. width: 60mm
