I've printed lots of bottle openers from thingiverse, and they all work, but I decided I wanted a better one:
- No metal: does not need a coin or other metal parts
- Opens bottles easily and quickly
- Durable, can open lots of bottles
- Ergonomic, fits in the hand well
- Does not bend the cap
- Small enough to fit in pocket
- Easy to print
This opener uses a curved prying edge that catches on a substantial amount of the sharp cap edge, the extra contact spreads out the opening force, so the opener is much less likely to be damaged by the cap edge.
The cap lever covers the whole top of the cap to keep bending to a minimum, and the lever lip forces the cap into the opener so you only have to lift vertically to the bottle.
Since the cap is barely deformed you can (in most cases) put the cap back on the bottle and save the rest of your beverage for later.
This is version 9 and I think it works really well. If you think you have a better opener design, comment here and I would love to check them out.
Print and enjoy a beer.
Print with a 1.6 to 2 mm shell, and 25% infill or higher.
Having a thick shell is probably the most important part.of making the opener durable. I've opened around a hundred bottles so far with no problems.
