Nice project. Are you publishing the PCB files?

I'd like to use them with the Kelvin Clamps which I will modify to make the leads pluggable.

Great solution to those very small components.

Hi Frank,

Very interesting adapter! I didn't think it was possible to 3D-print a mechanism to grip such an SMD part. Really nice design, and they look so well made I would not have realized they were home-made from the photos.

Great color scheme too!

Very well done project and blog! I really like your attempt at an SMD clamp for holding the part in place while you measure its value. I wonder if a flip-top adapter (similar to programming adapters for smd chips) could be fabricated cheaply as another approach?

Another idea might be something along the idea of a 4-jaw chuck, like on a lathe, scaled way down, to hold the device under test?

Another enjoyable and informative blog, keep up the great work!

Really good work Frank. Looks like it would be a good addition. At the moment I have to use large Kelvin tweezers and they are awkward to get a good contact on 0805 parts.
