I liked the dome shape of DL9HAM's Xiegu G90 speaker redirector, and the elegance that it did not need supports to print, but I wanted something less permanent that could be put on/removed easily.
Inspired by this clip-on stand, I used a similar style/shape redirector, but added a bracket that spans the back of the radio and clips into the cooling fins on the side.
This fits the newer-model G90 that has 7 cooling fins on either side.
The author remixed this model.
I used a similar redirector design but added a bracket that allows it to clip on to the radio.
