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!

Print Settings

Rafts: Doesn't Matter

Supports: Yes

Resolution: High

Infill: 60-100%


Material: PLA
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

How I Designed This

2D Drawing

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)

Finishing Touches

Lastly I used 123D Design/Meshmixer to edit and refine the 3D creation!

Strange; the model looks like this when I open in it Repetier-Host: https://i.gyazo.com/bb2e81ae08ee3bccf227348bb5abce2a.png
It sliced just as badly as it looked: https://i.gyazo.com/ce67894fd890e48af5e794fd48da4a21.png

thanks a lot for a model!
first I've failed to print it with Slic3r, it suddenly stopped after the half of handle,
printed it successfully with Cura.

I might just muck with this a bit! I've got this little tool from walmart.. it has a soda-can-tab-wide angled end, and then before that end, a little tab has been cut from the metal and bent upwards almost 90 degrees. It's exactly a third of the width of the end angle, with the top hooked towards the angle end. This smaller tab is bent out on the same side as the inner curve for the end angle. You put the big end angle down onto the soda tab, and then hook that smaller hook under the end of the tab. THen just hold the can while lifting the tool off... totally pops the can open! All you need to do is fold the soda tab back down and drink. This tool of yours, the soda pop end can easily be redesigned for that! Then it would make ALL those fluid containers drop dead easy to open!

amazing havent printed it yet but soon

Side note: I don't know what kinda crazy cheap filament you're using, but $17 is about 1/2 what I pay for filament :)

I buy it in bulk off of ebay. From my test the pla I buy is stronger than the ones I bought from robo 3d. No issues with it at all :)

This almost seems designed with an inherent weakness for the bottle opener. Here's what happened after I used the bottle opener about 6 times:


Cracked right at that spot

Are you using 100% infil and high quality PLA? I have used it many times with no issues.

You know, it's possible I didn't print w/ 100% infill, like a dumbass :)

lmao, don't mean to laugh, but that reply was funny as hell!

Yes, it doesn't take much more material/time to print at 100% for this design. Highly recommended :)

Have not analyzed to model for the errors/problems others have mentioned but just wanted to say thanks for doing something like this. I am myself diagnosed with severe arthritis and will lose more and more dexterity over time. This is the reason I myself got into 3d printing and design, to develop and make simple tools to make what most take for granted accessible again.

Glad you like it! As for the errors, I have done my best to correct/lessen them. I am not a professional designer. As long as you are not using Slic3r you should be okay to print. I ran the .stl through mesh lab in order to lessen the polygons, and ran an auto repair on netfabb. I hope this has helped some of the issues. Thanks for your comment!

Model does not appear to be manifold or correct normals, and has problems slicing with Slic3r.

I am not sure why Slic3r is having problems rendering the model. I have tested it in several other slicers with no errors. Also, any attempts to repair the model have had no effect. If I find a way to fix this problem I will upload the repaired model.

The model has a massive amount of redundant polygons probably why, modo can't find any errors in the model but there are also really weird sections of polygons being cut through by curves, the hole is split inside doubling it's faces and some parts inside have absolutely massive amounts of polygons, one flat surface inside the hole is 60 polygons all at the same angle, could be 1, etc etc. Total of 49070 polygons, it needs about 5000 I'd guess to have the same shape it does currently.


I mean just look at it, so many redundant polygons everywhere, what did you make this with?

Well done, In3Designs. This is very thoughtful of you and also practical for many people.

Thank you for the nice comment! I'm glad you like it and find it useful!

Very Nice Work, that is badass good invention:)

Great design! Fantastic thing to print as a giveaway for friends. Thanks!

does it require supports?

I would recommend using support to get a better quality print. The teeth may not print correctly without it.
