I just created a simple 3D printed holder for a single Flic.

I keep one of my Flics in my pocket, it would regularly get triggered accidentally. Because of this I wouldn't use the single-click action, although my long-click would often get triggered as well. This holder covers the flic and leaves a large hole to press the button decisively, only when I want.
