F|F Research & Concept

This image from Thingiverse is of a 3D printed bottle opener. It is used to manually open glass bottles with metal caps. The small size of this bottle opener makes it convenient to travel with, as it can be made to go onto a keychain, or can simply fit right into your pocket. The bottle opener has a unique feature with a hole for your finger so the opener can be easily maneuvered to remove the bottle cap. The other side of the opener has a hooked end that goes over the bottle cap and applies pressure on it for removal. The image above displays how your hand can fit into the bottle opener and how it is used.

Potential improvements I might make to this bottle opener would be to add a second hole for the middle finger. I think the addition of this hole will allow for more pressure to be used to open the bottle with even more ease. It also increase the stability you would have on the bottle when opening it. I increased the length of the bottle opener slightly to accommodate for the second hole. For a personalized touch, I would add a very small hole at the top of the bottle opener to allow for it to be placed on a keychain.

F|F Iterations

The creator of this model of a 3D bottle opener is Mark Manger.

After printing the original model and testing its functionality alone, I found that my initial remix concept to add an additional finger hole made it more difficult to open a bottle rather than less. The curved open end that follows the first finger hole on the original model allows for more pressure to be exerted on the opener. That extra pressure is needed to force the cap off of the bottle. The length and infill of the remix needed to be altered more for the iteration to work properly. While the double finger hole might not have worked, I did add some additional features to the original bottle opener. I glued a coin onto the bottle opener end of the model to provide a better anchor to lift the edge of the bottle cap. I also added a keychain to the petite hole at the top of the bottle opener by expanding the hole slightly.

Final Print

For my final print of this model, I decided to re-do my original iterations with a few added changes. My original idea to add an extra finger hole was not successful at first. However, I altered the length of the bottle opener to be slightly longer and I fixed the positioning of the extra hole on Tinkercad. I downloaded the final remix as an STL file and I was able to print a working model with a larger infill of 30. These added alterations allowed my final print to function successfully. I glued a coin onto the end of the final print just like the original model.
