Meh, it'll do.
The product is clearly made with a 3D printer. Kinda rough but usable. You get a little bag of parts. No instructions of any kind. Being of the engineering persuasion I did learn that you have to remove the front and back panels from the nanovna. Then you have to force the board assemblies into what are more like picture frames than a proper enclosure. I had to do a bit of force fitting. I plan to get at it with a small file later. As it is, the top and bottom "picture frames" don't fit together well. You reinstall the front and back panels onto the board assemblies in order to hold it all together. The little storage spot for the cal standards is a nice touch. So, in the end, my nanovna is protected from general handling and larger debris. Nothing to write home about but it will do.
