NanoVNA Calibration Dongle

Handy tool, to keep the SMA calibration connectors together so you don't lose them.
Also makes it easier and faster to do the calibration.

The SMA connectors fit perfectly into the holes without any glue.

O = Open
S = Short
L = Load

No supports needed.

I have printed it PETG, but PLA should work just fine as well.

0.16 or 0.20 layer.
