You can see my make here: https://www.thingiverse.com/make:427249 that demonstrates what i describe below:

The Triumph stalk is very easy to snap, take care of it at all times when handling the model.

Print the frame with 3 walls and decent amount of infill so the prop hubs don't break off too easily and to give the antenna some strength.

Use a 5mm drill to smooth out the props hole then press fit using a vice so it has a strong friction fit with the frame prop hubs, to prevent it coming off too easily.

The hood slides very tightly between the antenna stalk and fits OVER the camera, so slide it over the camera while supporting the stalk and friction fits into place. I would recommend flowing some super glue into the interface between the stalk and the hood, also the frame and hood base. This will help support the stalk, making is less likely to break.
Alternatively if you break the stalk, or prefer, use some thick black wire, cut the stalk off and drill a small hole in the head of the Triumph and into the frame. Push the wire into the holes and glue the black wire between them. This provides a realistic pose-able antenna that will not break and can be angled to be at a more realistic angle too -I liked this "enhancement".

Thx for the feedback. I like your antenna mod :D

I also used a wall thickness of 3 lines and some hot glue to stick the canopy onto the frame.

The props should provide a tight fit but that also depends a bit on the material used.
