Sweep/Loft General Question

Hello,
I'm attempting to create a small air manifold, and create 6 holes that merge into one.
I'll continue to search and experiment but would love to see the different ways to achieve this.

Thanks for your time and knowledge sharing!

Not the most elegant solution, but by projecting the intersection of each hole onto a sketch I was able to create a chamber using loft.

Here's a simple way to do it using multiple sweeps.

@eric_pesty I was trying to do all 6 at the same time, your solution is brilliant! Appreciate the help. I'm going to continue trying to tinker with the design. My goal is to 3D print it in TPU. Perhaps your solution would print fine with stringing, or 'good enough' for my purposes, however I'm going to keep playing to try and use your solution at some point (maybe halfway up) and then have it open up to a larger chamber? not sure what it would look like. Right now I tried that in combination with shell, but then everything got messed up. I'll keep iterating. Appreciate the community support!

If you don't care what happens inside you can do something like this:

You might get "cleaner" results if the bottom corners were concentric with the corner holes like this:

Matthew_Curran thanks for that solution! In your "Chamber" folder, how did you create the "Sketch - Bottom of Chamber" with the six circles aligned to the inside of the chamber? I see your constraints in the sketch, but how did you align the six circles? Did you do it visually by hand?
eric_pesty thanks for an additional solution. I haven't thought fully about what is req'd or would work for my application. The manifold is bringing in (6) 1/4" diameter air lines supplying ecig vapor. They funnel down to one, and ultimately for use in MRI for human participants. This is going to be iterative and maybe I can save material and use your second solution.
Appreciate the knowledge! Thanks!!0 -
@yuggniiks I did that using the "Intersection" sketch tool. I selected the tool then clicked on each face of the 6 holes. It will project the intersection of that face on the sketch plane.
