My mother was diagnosed with Cushing syndrome over a year ago. Along with many other symptoms muscle deterioration is one of them. She has been treated and is on the road to recovery but she is still very weak. She was telling me that she had to go to her neighbors house so they could open up a bottle for her. She had a bottle opener but not one that would fit a large bottle. I went through a few different designs but now I have a working version.
The "Universal Bottle Opener" or "UBO" can open large juice bottles, sports drink bottles, soda bottles, canned drinks, and pop tops!

It is recommended to print with support so that the teeth can be printed correctly.
The support should come off fairly easy depending on your slicer/settings.
Infill: If you plan on having repetitive use it is recommended to use 100% infill..
Cost per unit based on a 2.2lb spool at $17.00
60% infill: $0.37
100% infill: $0.46
Slicing Errors: It has been reported that some slicers do not correctly slice UBO. This will be fixed if possible. If you are having issues please try the "KiriMoto" app located under that apps section of UBO or download MatterControl.
As most of my 3D files it started as a 2D Drawing.
2D to 3D
From there I like to use the "Image Converter" feature on MatterControl.
(There are several websites/software to get the same result)
Lastly I used 123D Design/Meshmixer to edit and refine the 3D creation!
