Extender handles for the fRsky X18 specifically to fit the Ranger ELRS module on the back for the 2.5 watts of goodness.

Probably works on x20 series as well? I highly recommend to print it at an angle, my first handle snapped off cleanly after a few weeks of usage when printed flat. you press fit the handles into the radio itself, you can use glue if you want, it might be a good idea to run some glue inside the handles when you run the antenna's through them.
