This object allows for easy opening of water bottle caps. The toothed surface grips onto the roughness of the caps, allowing the bottle to be opened with less force.

It has an almost triangular and rounded shape, without edges or sharp parts, making it ideal for children or people with various types of mental or physical disabilities. The object can be printed up to about 10-20% larger or smaller without losing its functionality, to accommodate hands of different sizes.

It doesn't need supports.

Update: as it's the second time that someone 3D prints this model to open almost-smooth COCA COLA caps and then is unhappy with the results leaving bad reviews, let me explain that the TEETH you see in my model are there for a reason: they grip onto the ridges on the cap, present on the vast majority of water bottle caps. So please, keep this in mind before pouring your frustration onto the designers who are sharing for free their designs with you: instead, please be sure to check the description/photos/videos of the model you are going to 3D print and ask yourself if it's what you need. Thank you.
