Protector cap for RP-SMA

This is a protector cap for a RP-SMA (Reverse Polarity SMA) female connector. For example, as used by the Behringer XAir XR18/UR18 Wi-Fi antenna. Note that the cap is a press-fit, which works very well. The model does not include a thread. I have printed it in Transparent PETG for my mixer, as shown in the photo.
