About this 3D model

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) Boost Me If you like this design, your free Boost would really help me create more designs!
