Summary

Simple case for nano VNA that includes an outer sleeve and an inner tray for storing a nanoVNA and a handful of its accessories - SMA adapters and cables.
The pictures are of the first version. I added a few features in v2 to make it easier to insert/remove the tray, and to allow you to orient the nano VNA with the wristband toward the outside.

I printed this with Inland PETG+ and also with Inland Tough PLA. Both worked well. The Tough PLA tray looked better in my opinion. I allowed (I think) 1mm difference in dimensions of the tray vs the interior of the sleeve which allows a perfect amount of resistance (for me anyway) keeping the tray from falling out.

I feel it could be improved with thinner walls or less infill to make it lighter and to print faster.

Please modify this if you can make it better, and share!

For reference, my nano VNA measures 133mm x 75mm x 18mm. (not including the switches on top) So if yours is the same or smaller this should work.
