Someone in a facebook group shared a trigger guard they had made out of an item they bought, then glued to their NB4. I thought it looked cool, so I made a couple of my own.
The first one attaches at the top, where you might see several of the gopro mounts, and then at the base of the handle by going around it and bolting it through.
Then I thought I would make one thats much more custom to how I use the noble. I never use the external battery, and such, made the second version attach to the external battery port at the bottom of the grip.
Both versions are included in the download at thingiverse if anyone is interested.
