I used 1.6 mm PCBs above and they work OK, but if available I might try slightly thinner, say 1.2 mm if fabricating new ones. That might make it easier to guide the fingers into the slots yet still allow them to be firmly held in place.

Forgot to put the STL files on github. That has been done now.

Nice build to extend the capabilities of an instrument. Thanks for sharing.

Kind regards.

Great job Frank. I think tweezers would be good for small SMD parts.

Hi Frank,

This looks great! And probably better than ready-made adapters, since you have the shielded cables. Those Kelvin connectors are pretty good, I purchased a few on their own, and they are also handy even as general-purpose alligator clips.

Very nice and very clean. You have done an excellent job in your fabrications. Nice to see you making use of your heat set inserts. Well done.

I have a client that builds Kelvin probe sets for older model HP meters and sells them ebay for ~$250.00, so there might be a great business opportunity for you in the probe business.
