this is a redesign of a design I found linked below. This is for people who struggle with opening bottles and cans. The advantages of my design over the original are that it has sharp teeth, so is less likely to slip. and the finger grooves are more spaced out, so it is more comfortable to grasp.

I designed this using fusion360 and printed it with PLA (Nozzle: 190C, Bed: 60C)

UPDATE 02/02/24: 'twista 2' yet to be tested, instead of relying on forcing down the handle, you can twist it backward as you push making the bottle cap wedge into the handle, also increased size of cap hole as it 'my version' is too small, but still works on caps sized D=2.5cm or less
