C414 EB-style capsule mounting?

[OneRoomStudio]

I'm building a pair of Vamisound V-414's (more info here), and I'm in the final stages now that I got a beautiful pair of CK12-style capsules from @OPR. I went to install the capsules, only realize that I don't have a good way to do so. Mark supplies the brass saddles with his capsules, but no mounting posts, and I'm not sure if I want to use mounting posts anyway. Real C414 EB's used some kind of plastic/rubber mount, as seen in these pictures:





The Vamisound instructions show a post instead, but it looks to me like that would place the capsule too high up:


Thoughts? Anyone have any creative ideas? I suppose I could try to have something 3D printed, but I've never messed with that before.

I used a shorter saddle from AliExpress in mine. These

@Tim Campbell I read somewhere that you make (or made) 414 capsule mounts. I know you're too busy with OEM orders to sell your capsules to us punters, but maybe you'd be able to sell me a pair of mounts?

Well, I gave a shot at designing one to fit into the usual Chinese 414 body (as seen on the Vamisound page).



It's 8mm tall in total (2mm flat and then 6mm slanted), and it's designed to fit on the metal platform in the body. I added spaces for two captive M2 nuts on the bottom (to attach it to the metal platform), and one captive M3 nut on top (to mount the saddle to). The round cutouts on the sides are to allow capsule wires to be routed down through the holes in the platform.

Printing it in TPU 70-A, which seems like it would have a similar Shore hardness to the vulcanized rubber or whatever was used in the original, would cost about $40 per mount. Not cheap, but not terrible for a custom part.

I've never done this before though. Anyone have experience designing for 3D printing?

That doesn't provide a way to suspend/mount the capsule.

Damn It !
You beat me to it, I was fiddling with something like that just today on a 3D software.

@k brown :"That doesn't provide a way to suspend/mount the capsule."

Yes you can. Put either a rubber cylinder (a bit too high for capsule ) fixed on that Hexagonal hole in the middle .
Or use those metal U shaped'ish adaptors coming with some C12 copie capsules.

As I mentioned before, Mark (OPR) provides vintage-alike brass saddles like these:

...which would be attached via an M3 bolt screwed into an M3 nut embedded in the hex cut out on the top of the mount.

i can get it made out of my solid neoprene blend for dirt cheap if you guys want, just make sure the model is totally accurate

Are you talking about the beveled diffuser below the capsule, or the capsule 'slung' suspension?

Are you alking about the beveled diffuser below the capsule, or the capsule 'slung' suspension?

the former, though the latter would also be no problem

I would like to see more DIY stabs at that AKG style capsule suspension; I've taken a few stabs at it, but not very successfully.

i will do anything provided people want to send me samples to make my own drawings of. can't promise it'll necessarily be cheap though now that we're doing it ourselves

Re: the beveled mount/diffuser - I want to add holes for the other wire pass-throughs just to be sure, and then it would be great if someone would check my work. I can probably upload a .STL or .SKP file tomorrow.
