This is a hard case for the original Nano VNA with dimensions approximately 91x62x17 mm (excluding the SMA sockets).
Working hinge and catch. Storage area for calibration accessories and guitar pick.
I suggest measuring your VNA before printing, especially if your rocker switch protrudes a lot. As the VNAs don't seem completely standardized I've added a few mm clearance. You may want to add some foam or rubber to stop excess rattling, or you could modify the parametric file.
Suggested print settings for PLA: high resolution, 60 mm/s, 100% fan, no supports.
