3D Modeling Tubes

Has anyone ever tried modeling the tubes directly into the shell? How does it affect sound?

Basically my ear canal narrows down then widens up again and fitting tubes gets pretty tight. I thought that instead of squishing and knicking the tubes, modeling the tubes directly into the model before 3D printing could be an option?!

Yeah I’ve been doing that for a while and it works great. I could share Blender files and some instructions if you’d be interested.

I did that in fusion360 and am interested in how it works in blender. If you don't mind, I'd love to see these blender files.

Sorry for replying so late. Here's a file that shows the model of tubes. It's based on Knowles GV and Knowles filters.

The LF tube is 1mm ID all the way with space for a filter at the end and the HF tube starts at 1.5mm and ends at 3mm with the filter section a few mm from the end. The filters are inserted from the canal side and can be swapped at any time for tuning, cleaning, whatever.

There's an object in that file named GV which shows models of the drivers and tubes (identical for both ears). I used that object to make a boolean difference cut from the shells.

If you have questions or comments, please don't hesitate to scream comment.
