You should be able to assemble a suitable pin array from mil-max 3150-2-00-15-00-00-08-0 or 3330-2-00-15-00-00-03-0. A PCB structure is robust enough to support and align an active interface as in here: https://www.eevblog.com/forum/projects/diy-100mhz-differential-probe/

Mill-max 3330-2 looks like it could work.  Thanks!

Did they work out in the end?

Folks,

Many of the plastic tabs seem to be broken off on my older active probes.   I an effort to solve this problem, I took some calipers and created a 3D model.   .STL attached in the .ZIP file. 

To test fit the model, I printed on a FDM (Prusa MK3S) using Prusament Galaxy Black PLA filament.   The results were much better than I expected.   The fit is wonderful and after mounting it to an existing probe chassis, it feels like brand new.   Tight fit.   

Side-note: the back-side of the original connector appears to be covered in some kind of metallic paint.   I've found a few options, but haven't tested any of them yet.

I suspect printing on an SLA would produce better results, but alas, I don't have one (yet..).    If some one does, would it be possible for you to print and post pictures?
