SMA Calibrator Holder

Simple holder for SOL Calibrators (SMA) for the NanoVNA, but should work fine for any SMA-based (8mm) calibrator.

With my printer, the calibrators slip in snuggly, but not tightly. I wanted them to be easily removable so I didn't resort to glue or heating to force them in. Instead I put a small ball of beeswax in the bottom of the hole which is sticky enough to securely hold them, yet they can easily be pulled out of the holder for replacement. You could also use Blue Tac or Glue Dots. You can glue them in if that doesn't bother you.

The F360 file is provided. It's not a complicated model so changes are easy to make.
