Custom breathing straw

in Wearables held by Philip W
Contest Ended, Winner(s) have been selected.
Description:
I use a machine for breathing assistance with a "straw" mouthpiece. Unfortunately, the one I designed myself and currently use isn't working as well anymore. I got my face 3D scanned and I want to make a straw for the machine that's custom shaped to my face. You can see in the side view that it doesn't fit my face correctly.

I know this is a medical use case, but I will only use your model if I think it's safe and I take full responsibility for any consequences of using it.

I'm attaching all 3 scans that were taken - use whichever you think is most accurate. I'm also attaching pictures and models of the straw I use currently.

Specifications:
* 1/4 inch outside diameter
* 1 mm wall thickness
* 1 sets of side holes (left and right) with area around 0.3 cm^2
* 2 top holes with area around 0.3 cm^2
* part inside my mouth same as current straw model

I may ask the contest winner to make modifications after I try it on an hourly basis. I will also probably have future jobs as well.

Thanks for looking!
Wants:
Accurate fit to face scan
Correct diameters
Follows specifications
Solid/manifold model file suitable for 3D printing
Software:
  1. any
Additional Information
* The current straw file is in millimeters.
* Please post an STL, IGS, or STEP file in addition to the source file.
* Please round/filet all the edges.
* I posted more versions I've tried which didn't work for me.
* The part of the straw inside my mouth should match the curve of my jaw/teeth. See "mouth inside picture" attachment for details.

I'm printing your models and I'll test them soon. I'll most likely choose one of yours as the winner.

This has a path on a single plane. I need a 3D path which turns to the side inside my mouth, like entries 20 and 22.

It curves the wrong way. Everything else looks good - I'd like to try it with that change. Thanks.

What are the changes between each? I tried the first 2 but they extend too far into my mouth by 1-2cm.

I'm having problems with my 3D printer so I have to get someone else to print it. This means I can't test the designs as quickly, so I extended the contest by a week.

This looks like it's for the left side of my mouth, not the right?

Could you please upland an STL of the straw by itself? Thanks.

Could you please upload an STL file?

I mean that the path should curve on 2 axes not just 1, like entries 11 and 13.

Hi Philip, did you check my attachment? I already added 3d path only in STL format no other object please check..., I think you didn't check my attachment....Do you need IGES and STEP file formats too?

I'm only taking entries now with a 3D path (see my first comment on 4 Jun). If you modify and resubmit I'll test it. Thanks.

I actually meant the front part straighter. See attachment "11 - straw4 change".

After trying the current submissions, I realize that the part of the straw inside my mouth should match the curve of my jaw/teeth. See "mouth inside curve" attachment for details. With that change I'd like to retry all the shapes again because they might work then. Thanks.

That could help, but this is for people who are awake. Once I have a shape that works I might add something inside to keep it in place. Thanks for the input.

I think better design need an element in mouth for situation that patient is unintelligent an coma for fixing it in mouth with no need to adjust it for better utilization.

Are these 2 different?

I 3D printed and tested , , , and . I like the ideas but if they could be modified to follow a 3D path that would be best. I'd like the part in my mouth at the angle the picture shows and then for it to go straight down (following the curve of my chin) and then back going to the side of my neck. Thanks.
