NanoVNA Calibration Storage Box

Please like and follow and post your makes

This is a small secure matchbox sized storage container for your Nano VNA calibration standards that generally come with a NanoVNA device in the SMA form factor.    There are three positions and they are labeled Open, Short, Load.   Use Prusa slicer or other methods to insert color changes for your print.   There is a lanyard hole on one corner.   The lid snaps into place to secure.   You might consider using PETG for more durable heat resistance if this ends up in a hot car etc.   

I used standard profiles since this is a utility item.   No supports .4 nozzle.  15% infill.
