30mm Button Antenna Holder for Brook Wireless Board

I have a Brook wireless board and didn't like the idea of cutting into my stick when I often have spare button holes from door replacements. This lets you mount an antenna in any 30mm button hole, and uses threads to attach it to the enclosure

The threads are intentionally rather loosely toleranced so they can be printed easily on a filament printer, but they work just fine for securing the button.

I have variants of both the plug and the nut:

The original button length, a half length button, a tighter toleranced nut, and a loosely toleranced nut. Both work.
