Dual ring for easily opening the cap (only the most common size of approx. 30mm DIA) of a plastic/PET bottle.

Sizes
Five different sizes of hole for caps are available. (Only one size of hole for fingers, 22mm.)
I recommend that you try printing size “03-Medium” first. Then, if the size does not fit your bottle cap, try another size.
- 01-ExtraSmall ─ (-0.4mm in DIA)
- 02-Small ─ (-0.2mm in DIA)
- 03-Medium ─ (±0mm in DIA)
- 04-Large ─ (+0.2mm in DIA)
- 05-ExtraLarge ─ (+0.4mm in DIA)
