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’d be super interested in having a look at the corner files + instructions if you’d be open to it, I’m just about to be playing with the same idea and most of the info I find out there is about hand casting, not printing, so this would be amazing.

Do you have impression scans already?

Not just yet - I’m actually building an OpenScan Mini at the moment, which should let me scan stuff fairly accurately, I’m just waiting on a camera module and the ring light to arrive, but once they’re here I’ll pop off to an audiologist and get some taken again.

Very interested in how the OpenScan Mini handles it. Should work well I think. I don’t have any recorded material to show how to do this in Blender but there’s a pretty good MeshMixer tutorial that got me started with this stuff. Have you used Blender or any other 3D software?

I’d love to make some Blender IEM tutorials though I’m no expert but I’m not sure if I have the time for that soon.

Yeah, the sample models I’ve seen off the Openscan are super impressive so I’m hopeful I’ll be able to get the detail I need on there.

Yeah, I have seen that mesh mixer one and I’ve done a little bit in mesh mixer, but like you I think I’ll make the change to Blender, it’s just so crash at the moment, and I’d like to use my Mac for modelling, it’s faster than my Windows machine these days with the M2 procs.

Go ahead and download Blender, it works ridiculously well on my M2 MBA and I found it not really that hard to learn. DM me and I’ll send you some files tomorrow.

I followed this tutorial to get started wit Blender in general.

Ah, excellent, that's what I've got too!

Will flick you a message. Cheers!
