This listing is for 5 pieces 3D printed SMA connector finger wrench in the color of your choice.  Add these finger wrench to the SMA or RP-SMA connectors on the antenna of your Fatshark, Eachine or other FPV goggles to help you in tighten down and removing your antenna.  If you have any other questions feel free to message me.

The tightness of the wrench may differ from antenna to antenna, this is due to the variances in 3D printing as well as differences in antennas. If it is too loose you can slip a small piece of paper inside to make it tighter, similar to putting floss on a prop for motor. 

If you need a smaller size SMA Connector Finger Wrench, I have some listed here:
