You can get pretty smooth results when printing with PLA with a small mesh and smoothing it out with acetone vapors.
But agreed the lathe'd plexi is the most beautiful result !

I have ordered one, will see how the transplant goes!!
A lathe made one would probably very smooth
But with patience you can do it in a 3D printer.
Enable ironing and make it 100% filling
Then you need to sand the surface very well to make it smooth. Totally possible
Went on a little google bender and came up with this :
There's a lot of those on Etsy. Other search keywords are dome paperweight magnifier.
Anybody know the dimensions of the dome inside the ElaM?

it's not exactly a dome though, right?
All the pictures I find of internals look like this:

You would get the similar result, but if we go this deep, the screws, the stand and everything below the capsule will affect the sound to a certain extent. Also the exact height and the position of the capsule is quite important.

I have some feeling I've seen a drawing of the head basket internals but can't recall where now. capsule looks to be up quite high, rather than in the middle.... I think I will lasercut some stacked acrylic discs to roughly replicate the base — especially if I can work out how to bevel the edges.
I got a little distracted by the shiny lathe'd dome, but you're right. And thanks for the clear pictures. Looks like 3D printing would deliver the most accurate results here. It's also a hollow structure it seems. There's also the matter of accommodating the different stand options. I'd probably get a Beesneez CK12 for this mic (unless Tim has some good news for us in the coming weeks/months) which has a cylindrical rubber mount. And then there's the mounting holes on the base plate.
I still have some things on my agenda for the coming week but I will have plenty of time to figure all of this out starting next weekend.
The Neumann U67 used a dome shape,
but that's not the case with the Ela-M 251, it's not really a dome.
3D Print seems like a good option

I finally squeezed my proctop pcb in mine, kept not working and was the capsule connections touching the middle tube so I put some tape over them and tucked them out the way.
Put some thick rolled up wire in the bottom so when the bottom cap tightens it’s nice and secure and used the underneath washers to lengthen it so the pcb can fit!!

Damn I don't want to ask you to open it up again but do you have any pics of it open and how you got it to fit?

Early on in this thread they said about mounting the struts underneath and putting 4 washers to lengthen it, I did that and then you need to put something like a plastic pipe in the bottom so it tightens up. It’s on first or second page I think of this thread with pictures

Ahh thanks I thought I was up to date on the thread all along but I guess I missed it.

Always good to revisit threads from the start, I’ve got a stereo Neve 2254 I built but was a rats nest, I’ve started to rewire but I think I need to do the same and revisit my build thread as there are a few things I did which I can’t remember!!!
