RigExpert Antenna Analyzer Bracket

This is my first attempt at designing a part so it is a work in progress. I have a RIGID case with my FT-857D mounted in it. My RigExpert AA-54 was held in by velcro so I designed this bracket to hold it in place. I printed in PLA as that's all I've used at this point and everything seems to fit. Something a little less brittle may be better.

I am holding it in place inside the case with 3M VHB.

If you print it or have any suggestions on how to improve it I would be glad to hear them, I'm just learning all of this.
