SMA Calibrator Holder

thingiverse

Simple Holder for SOL Calibrators (SMA) designed specifically for the NanoVNA, but adaptable for any SMA-based (8mm) calibrator. With my printer, I found that the calibrators fit snugly into place without being too tight. This allowed me to achieve the perfect balance between secure retention and easy removal. To prevent them from shifting or falling out, I inserted a small ball of beeswax at the bottom of the hole. Its sticky surface provides a firm grip, yet allows for effortless extraction when replacement is necessary. Alternatively, you can use Blue Tac or Glue Dots to achieve the same effect. If you prefer a more permanent solution, gluing them in place is also an option. The F360 file is provided for your convenience, and its simplicity makes it easy to modify as needed.
