C414 EB-style capsule mounting?

[OneRoomStudio]

If you want some advice, use the Neumann circuit for the U47 with the 6CW4 nuvistor. I believe it is the best overall, considering the original U47 FET and U87, which I have owned for years.

This thread is about a C414 EB

yes i know , but if you want do a new projet , remember.

I will keep that in mind, thanks.

Here's a model taking those measurements into account and adding additional pass-through holes. This should be accurate. Anyone want to check it? @soliloqueen - what would the rough per-item cost be to do these in neoprene?

FYI, I attached a .stl file, but to attach it, I had to use @MidnightArrakis's method of adding ".pdf" to the end. Just delete that, and the file should open. Also, this file is in mm - since it's easier for me to work in, and it's for a European mic anyway, haha.

In bulk? Maybe like 50 cents for a small amount. Like 15 cents for a large amount. It's the mold that would cost money, not sure how much for something with this many holes in it

[MidnightArrakis's method of adding ".pdf" to the end] -- THANKS!! for the mention!!! I appreciate that very much!!!

[Anyone have experience designing for 3D printing?] -- You may want to contact @ruffrecords about 3D-printing. He has recently gotten into it and he has discovered that depending upon the type of filament material used and some other factors, that your hole dimensions will end up being printed -- a smidgen smaller -- than your intended dimension. IIRC.....and, at least for his projects, Ian had come up with some manner of an "offset" to counteract the 3D-printing error. He can go into much more detail about all of this than I can. I just design stuff.

Somewhat recently, I have imported some of the -- STL -- files that Ian had posted here into my SolidWorks Premium program and tweaked his files a bit in order to get his hole dimensions to a point that worked for him. I think it took the two of us only 2 or 3 iterations to hone-in a final dimension. And, like you had mentioned earlier, I then resaved his updated "STL" files and added-on the "PDF" extension in order to attach and post it here on this forum.

I'm good.....

Thanks, @MidnightArrakis, those are some good tips. The place I'm thinking of making some prototypes specs +/-0.25mm tolerances for SLS manufacturing, which should be fine for this. I think I'm going to order a pair (it's a $70 gamble, but worth it in my opinion, compared to the price of the capsules that will be mounted on top).

@soliloqueen - if these prototypes fit/work well, feel free to use the 3D model to make a bach for sale. I don't know how many people are building 414EB clones, but maybe there's a niche market?
