This is a model of the antenna cover for a Motorola Talkabout T5820, but it may work for other models. It should fit just fine, but some slight sanding or filing may be required to get it perfect.
All my prototypes have been PLA, so I'd recommend going with that. I think any material would work, but PLA is already stronger than whatever Motorola used.
Fusion 360 Links. If you think you can do better.
