it also seems the phase data is WAY off. don't know how to really get that reading correctly.I also made an impedance jig, that calibration is tricky too in REW, but I got good results and can test zobels:

I have three pair of the round SR Knowles driver that is a balanced armature BUT is designed to replace/ "upgrade" from a dynamic. My question... How in the world are you supposed to get the sound from the armature to the ear canal? There is no spout and just like a tiny .5mm hole in the center.... any advice would be of some help.
Or, I could 3D print it…..I used heat shrink tubing - shrink a portion of it but use the non shrunk part to hold the driver. Or you can get aluminum driver holders made for dynamic, with a tube spout. Cheap enough, but you still have to wait for them to arrive.
Plop the tube flat around the hole then apply adhesive. Make sure you use industrial grade adhesives tho.I have three pair of the round SR Knowles driver that is a balanced armature BUT is designed to replace/ "upgrade" from a dynamic. My question...

For y'all to play around with if you so choose. lol. That SR driver is so weird just gluing a tube flush... I felt better doing it with something like this. I attached the STL and the IGES so y'all can foul with it however you like. After you download them, change the extension from txt to either STL or IGES, same as with other components posted in here previously.Plop the tube flat around the hole then apply adhesive.

that's what I do with them.
Are you importing your impressions before or after the digital trimming process (via meshmixer f.e)?Anyone got ear impression scans into Autodesk Fusion yet? It worked for my left ear, but my right ear has some very tight creases, which makes the T Spline Faces intersect when thickening it, I cannot convert it to a body :/
I converted my STLs to quad meshes with Blender, this way Autodesk can convert it to T-Spline.
Also, I made the ID of the sound spout coming off the SR to be equal to 1.14mm. Wanna know why??? Cause I bought I thought I'd be smart and get those teeeeeny tiny dampers from Knowles.... Yeah they fit into nothing really and kinda fall apart when you look at them. This gives me hope now. LOLFor y'all to play around with if you so choose. lol.

Thanks so much for the thorough advice! I used Blender to convert to quads now. This kinda destroys the sharpness of cuts, but I just plane cut them again in Fusion nowAre you importing your impressions before or after the digital trimming process (via meshmixer f.e)?
I assume once trimmed and smoothed, the tight bends and creases should not be there so it would be less of a problem.
You can also use Instant Meshes (this is can be downloaded from github: https://github.com/wjakob/instant-meshes ) to transform the obj to quads before importing to fusion360.
Speaking of which if anyone is interested, there is a rather nice android/ios app for sculpting digitally I can recommend called Nomad Sculpt. Meshmixer is really the best and simplest tool for trimming but the sculpting brushes are lacking (no easy masking option as well as some brushes intensity, behavior and control is not that great). One could export midway processing from Meshmixer to Nomad sculpt to do some arrangements with brushes and import back in Meshmixer for final smoothing, thickening, hollowing etc...
Nomad sculpt learning curve is much lower than Zbrush or Blender and does the job. The brushes are good and using low values allow for small work to be done nicely. The 2 main brushes I recommend are flattening and smoothing. Flattening mainly used as a scrapping tool ( a bit like you would Dremel regular impressions). Flattening in meshmixer is rather bad and I never found a a good balance with it. There is a nice Scrape brush in Blender that is quite nice but Blender's learning curve is annoying...
I really don't recommend doing the trimming part in Fusion...I have no idea about the smoothing that way and what features of the ear it can crush along the way.Thanks so much for the thorough advice!
