I have large ears and 2 tubes 3mm OD and 1 tube 1.5mm OD is a real PITA.Yea but i think it will be hard to do more then 1-2 tubes for me
does the volume of air in the shell matter?less bass, as @Cevisi said.
Also on some case, u'll get some kind of distortion/weird resonance as a bonus, lol.
try to give the vent some space to breathe.

Glad you could find a real pro interested in this stuff The only one really intrigued by all of this was a trainee here.Here we go i take impressions by an audiologist a few minutes ago she asked me for what i need them i said i want to build ciems by my self she was pretty interestet and gave me an tutorial she was laughing all the time from where i know dreve and knowles she told me how to make the shells and yes we all do it right like an profesional she was astound that i know how to do it but we make one fault she said there is acryl from dreve that is light harding but not transculent and it will make a 1.5ml tickness shell from it self even if you put it for and hour under a uv light
She said they are ready to go i pre cut them just dont forget to dip them in wax 2 times before you make the mould
Now iam try to build my first shell
Damn i should not mess with it then... Mine are even less largeI have large ears and 2 tubes 3mm OD and 1 tube 1.5mm OD is a real PITA.

Another question can i do a shell whit endplate and dont do drivers or bores in it and use it as impression or should i just work whit the sillikon impressions

With every mold you will lose precision, I have tried to do one "blank" with no drivers and then use this as a mold. Doesn't work like that, sadly.
What I have done though is use an expensive a/b silicon to do the negative, then you can use the negative multiple times.

I think it was this one definitely dreve and thats the only yellow one

Ok thanks i already waxed it and cast it i will look whati can do at the finish shellThis is the most necessary pre-sanding with a stone or sponge drill. Maybe add some material at the socket faceplate area.
Yea i should be drill it first i took it like it was and waxxed it
Frirst shell turns out pretty nice no bubbles very clear 2 minutes uv and another 2 minutes turn 180 degre after that i poured the acryl out and let it dry for 3 minutes
Yea i should pre sand it a bit more and i think that was a bit too much waxx i diped it two times
Its a bit ruff to insert i get it in my second bend but there is a pressure on my ear i will sand the corners whit my drill
I think this part was not necessary ?
It is, but significantly reduce in size for easier insertion.I think this part was not necessary ?

Got a decent result with the 30017, with good air and nice extension. It will still need a mid, theres no way I could get the midrange frequencies up 10dB. This will likely need to be in the canal, based on tubing length. FR looks like the A/U12
4.5mm of 1mm tubing, goes into 4mm of 2mm tubing.
Hint: Use an ED with a long tube to shift peaks for mid

Hey hey,
i made a timelapse of 3D printing my shells. I got an awesome deal on a professional earmould scanner from Siemens. Check out the video.
If anyone wants their moulds scanned let me know. I can also print shells but you would need to pay for the biocompatable resin because it is really expensive.
Cheers

That looks awesome.
I'm really interested. How much $ do you think it will be ?
